Importance of a successful Recruitment ProcessIn the long-run a successful recruitment process is important to an organization in the following aspects:Time saving Having a predetermined recruitmen t process ensures that less time is spent when determining the best candidate for the position. As such the time spared can then be refocused to other crucial tasks.Saving resources This is in reference to both human capital and financial resources. A successful recruitment process will ensure that only the necessary and relevant people are involved in the recruitment process therefore freeing up others to do their jobs. It also ensures that money is not wasted on ineffective means of attracting candidates, for instance in advertising for the position.Consistency The recruitment process also ensures that the hiring managers use a standard process when assessing each of the applicants. This reduces personal bias and preference, and it gives equal opportunity to each of the applicants.Legal adherence A laid out recruitment process will guide the recruiters to selecting the best candidate while following the law as well as the company’s corporate policy. This is especially the cas e in public office where the law may stipulate a minimum requirement for a certain gender or other specifications. Cases of malpractice will also be kept at a minimum as recruiters will be informed of the conduct expected of them while running the recruitment process.Credibility An established recruitment process gives credence to the company by giving confidence to applicants that the position is genuine and they will not fall prey to con artists in the market. For example, if a company’s recruitment process involves applying for a position by first completing a personal profile online, they will be wary of counterfeit advertisers demanding something contrary.Transparency Recruitment officers and managers are able to follow the process and can account for the outcome. Also, it ensures that information on the process is available to all stakeholders and that applicants are privy to feedback and requirements of each step of the process.Recruitment metrics With tangible outcomes, the recruitment process is one of the measurable aspects of the human resources department. Therefore, recruitment metrics obtained from its analysis can be used to measure the success of the department and recommendations given on how to improve it.Learn about the KPIs you should track and report in your recruiting process.[slideshare id=52631307doc=recruitingmetrics-josebachvili-150910134020-lva1-app6892w=640h=330]Modern trends in the recruitment and hiring processAs the demographics of the workforce keeps changing in this fast-paced world, it is inevitable that organizations also change their tactics and strategies in recruiting to be better placed to address the changes in the talent pool and their changing expectations.To remain competitive and to be able to tap into top talent, you need to apply modern trends of recruiting. Let me show you how you can us these trends which are defining the human resources operations in the global market a;Employer branding More and more empl oyers are turning to social media to strategically improve their brand. This is partly due to a rise in prospective candidates preferring companies who have a more dominant social media presence and thus availing more information about their goals and objectives and what it is like to work for them. Candidates can then assess the organization and determine prior to application whether or not they would be a good fit.Use of talent data and metrics Organizations are increasingly using data and metrics to evaluate the success and efficiency of the recruitment process’ outcome. The quality of hire metrics remains to be the most used and preferred data. According to Sullivan and Burnett, quality of hire refers to a grouping of metrics that measure the degree to which candidates recruited and hired satisfy the requirements as defined. Quality of hire is being measured through performance evaluation of the new hires, the labor turnover statistics, and the hiring manager satisfaction.  T here is also a surge to capture rich talent profile data of prospective and former employees by use of talent sourcing technologies to optimize the recruiting performance.Referral systems Employers are making use of referrals in their selection of applicants as candidates with good referrals also tend to have longer tenures and better performance. Social professional networks have remained perched in marking quality hires, but referrals are peaking with its use illustrated in the graph below. Improvement of the candidate experience Organizations are seeking to improve the recruitment experience for the applicants by viewing it as a measure of business performance. They are therefore making it easy for the applicants to find and apply for the positions, ensuring the application process is brief and simple, interacting with the candidates before and during the recruitment process, and giving timely feedback to the applicants even to those who fail the recruitment. The push factors in this trend are realities of quality hires with multiple offers who will factor in experience when determining the company to work for, and also as a brand preservation measure. Candidates who have a negative experience are not likely to consider reapplying in future, and worse, may take their frustrations to social media platforms. Also, there are companies like Glassdoor which are giving candidates’ feedback and helping to rate organizations in their recruitment process.Use of digital and m obile communication Many of the current candidates are very digital savvy and prefer mobile technology in their communication. Organizations have realized this and are optimizing this factor by turning to similar methods of communications, for instance SMS and social media messaging. Also, with platforms such as LinkedIn and Facebook, organizations can assess the candidate from the information they provide on their social media pages and assess much more accurately if they are fit for the position.Video interviews There is a growing number of recruiters who have incorporated video screening as part of their recruitment process. This is especially the case in online companies who do not require the physical presence of their employees, or positions that do not require the same, for instance online social media marketing jobs. However, the trend is also picking up among more traditional organizations.Tips for companies looking to move with the recruitment trendsWith the above stated trends shaping the face of human resources globally, companies that fail to comply with the changes find themselves being edged out by competition and missing out on the best candidates. To make sure you do not get edged out, take the following steps:Create a platform for dialogue with candidates and prospective candidates This may be through an interactive social media site or via mobile services. This will help you get instant feedback and also attract more applicants.Focusing on the candidate  You must change your view of the candidate from merely a potential employee to a more holistic view. The candidate regardless of whether or not they fit the requirements for the current position is a client and a marketing agent. This shift in perspective will gear you up to optimize the recruiting process for current and future benefits.Digital and mobile strategy You must strategize on the best digital and mobile platforms to use in order to fully utilize their benefits in recruiting. This does not imply that companies must be visible on every social media page, but they must decide on the best way to represent their brand so as to attract the best hires.Learn about how Google recruits talent.[slideshare id=47765810doc=google-150505042952-conversion-gate01w=640h=330]THE HIRING PROCESS STEP BY STEPStep 1. Identifying a vacancy and evaluating needA vacancy may arise in an organization due to any of the following factors:Termination of service of an employee An underperforming employee may be cut out to give way to better and more capable persons to fill the position. It is important that the termination follow due process and be as professional and cordial as possible.Retirement of an employee Employees who have served the organization and have come of age may leave the organization and thus opening up opportunities for others to take over. As they leave, it is in the best interest of the company and common courtesy to treat the retiree respectfully and also com pensate them as required to avoid legal tussles and negative public image.Transfer of an employee to a different department This may be as a result of a promotion in order to better align the employee’s skills, experience, and education with the position. This then creates a void in the former position occupied and may necessitate finding a new hire to fill the same.Temporal leave of an employee This may be a maternity leave, paternal leave, or a more unprecedented sick leave. The nature and duration of the leave may influence the organization’s decision to hire or not to hire.Expansion of operations As a business grows and expands its operations, it is inevitable that it will require to also employ more personnel in order to cope with the increasing responsibilities.Once a vacancy emerges as a result of the above scenarios, it is important to first analyze the need to bring in more people to handle the responsibilities left behind. Some factors to be considered include:Relev ance of the vacancy It is important for you to consider the relevance of the position in light of the organization’s goals and structure. You must answer questions such as, how is this position contributing to the core business of the organization? Are there other positions playing the same roles as those in the current position? Does the position efficiently manage the current roles? This will help you to determine whether or not the position is relevant to the organization or is in fact redundant. Should you find the case to be the latter, it would then mean the position has to be done away with and resources directed to other staff.Cost considerations It is incumbent upon the hiring manager to determine the cost of hiring in the new position so as to ensure that the candidate selected is the most cost efficient alternative, not only with regard to remuneration, but also in the quality of service that he or she will deliver. Costs may include advertising costs, and consultancy costs.Streamlining functions of the vacancy It is important to do a job analysis in order to ensure the position meets the current requirements. Past functions should be considered and if need be, new ones added for more efficiency. Supervisory responsibilities should also be determined and on the whole, the responsibilities should be aimed at more production.Developing capacity of existing staff Organizations should also evaluate the benefit of new hires as opposed to the possibility of developing the capacity of existing staff by distributing the current responsibilities of the position to them. Should the benefit and cost effectiveness of hiring new personnel far outweigh that of the existing staff, then the position should be open for new candidates.Best practices when identifying a vacancy and evaluating needUse of metrics It is advisable for organizations to make use of data such as cost per hire, turnover statistics, and time to fill before embarking on a recruitment proc ess. This may help the organization to be better informed of the costs of hiring new personnel as well as anticipate how much time will be used in the process.Open-door policy Maintaining open communication with staff and managers will help the hiring staff to get more feedback on the position and how best to fill it.This is how much cost per hire can differ between companies, functions, industries, and locations. Step 2.  Develop a job descriptionA job description is a tool that outlines the required skills, competencies and education for the fulfillment of the roles and duties of a job.Functions of a good job descriptionIt provides the applicant with a first impression of the organization.It describes the skills, competencies and experience required for the role.It helps in managing the employee’s performance.It is also useful in setting the organization’s and employee’s goals.The job description provides a basis for the position evaluation and job classification.It is used to create equal opportunity and pay for employees.It is also necessary to avoid legal potholes. For instance, in America, where a position requires a specific physical ability, it may be necessary to exclude applicants with a hindering disability and listing this requirement ensures compliance with the Americans with Disabilities Act (ADA).Components of a job descriptionJob title It should be brief and should reflect the content, scope and purpose of the job.Position summary This gives a summary of the duties and responsibilities of the position, as well as outlining its purpose.Duties and responsibilities This communicates the expectations of the position and outlines the roles, tasks, and responsibilities to be undertaken.Job requirements and qualifications This includes the minimum education and experience requirements for the job, and also any certification and skills necessary.Relationships This stipulates the working relationships involved in this position, that is, who reports to the employee and whom the employee reports to.Physical demands This describes the physical demands and mental capabilities required in the job. For example sitting, squatting, bending, and lifting, and how often and for how long the employee is to undergo such routines.Working conditions This describes any conditions that the candidate may find disagreeable or uncomfortable.Steps in developing a job descriptionGeneral Information Describe the program or department and its purpose and how it fits in the organization. This information will help align the position and the general objectives of the program. Provide the position summary by describing purpose and overall objectives of the position and its responsibilities. This may be achieved by answering the question, how does this position support the function of the program or department?Identifying the major functions of the position This can be done by listing those tasks assigned to the position and categorizing thos e that are related. The major functions should then by arranged in order of importance. The next step is to determine the duration that will be spent in performing each function. Finally, distinguish between essential and non-essential functions of the position. To make it easier to identify the essential functions, the recruiting staff can consider the questions; does the job exist to perform this function? How much time will be spent performing the function? Can co-workers perform this function if necessary?Determining the qualifications required These are the minimum requirements that are to be met for this position. They should be relevant to the duties and responsibilities of the job. They should be specific and verifiable by a review of the resume. They are to enable the performance of the essential functions. Preferred qualifications are more advanced and above the minimum requirements. They are generally used to narrow down the talent pool for a better fit for the position. Determining physical and environmental requirements These maybe obvious from the tasks to be carried out. They are specific to the position and location of the job. It is therefore important to note any unusual physical demands or environmental conditions.How to write a great job description.[slideshare id=40761126doc=howtowriteastandoutjobdescription-141027054914-conversion-gate02w=640h=330]Tips for a concise position descriptionThe position description should be structured in such a manner as to reflect the needs of the organization.Gender neutral language should be used.There should be limited use of jargon, acronyms and technical language.The language used must be accurate and aptly communicate the requirements of the position. Vague words or those that may be misunderstood should be avoided.The requirements section should contain only the essentials as listing too many skills may reduce the talent pool significantly.The position description should be constantly updated to refl ect any changes that may have been adopted to the position.Focus should be given to the job requirements rather than the incumbent.It is crucial that the position description is shared by people who have first-hand knowledge on the intricate workings of the job. Managers and the incumbent may be brought in to analyze the final job description or earlier on in the process.Common mistakes in developing a position descriptionFailure to understand the inherent job requirements Inherent requirements of a job are the essential outcomes that are aimed to be achieved by the position. They are inherent if they cannot be achieved in any other capacity other than the defined position. Often times recruiters fail to clearly define the inherent tasks of a given position and hence fail to attract the right people.Use of subjective terms and opinions This is especially when describing the roles involved. Words that are subjective fail to communicate precisely what is expected of the candidate an d may cause frustration once the employee attempts to carry out his duties.Use of words that may be considered discriminative In an attempt to describe the desired candidate, organizations often make the mistake of using language that may well be discriminative. For example, use of the adjectives “youthful”, “able-bodied” and the like is best avoided.Out-of-date descriptions This may be a result of changes that have been adopted by the company over time which are not reflected in the position description due to neglect or lack of awareness of the hiring staff.Step 3. Develop a recruitment planA recruitment plan enables you to lay out a strategy to attract and hire the best fit candidate for the position. Make sure to include the following elements in you recruitment plan:Posting timeline This may be predetermined by company policy, open until filled or an ongoing recruitment.Placement goals These are determined for every placement and are reviewed in order to streamline the plan to achieve those goals.Additional advertising resources There are many platforms for employers to attract candidates. They include online job boards, social media, print advertisement, job fairs and campus recruiting.Agencies These represent marginalized and under-represented groups and help widen the talent pool.Resume banks These are a ready source of resumes and companies can easily sift through already available resumes to find the best fit.Steps for developing the recruitment planCreate a timeline allocating time for each activity from the date you must fill the position back to the day you will advertise the position.List the position or positions to be filled alongside their descriptions and requirements.Determine the best method of advertising for the position and outline the costs.Tips for developing a successful recruitment planEmployers should make use of market research data to find out the most efficient means of advertising and hence attract a wider pool of candidates.While setting time lines, it is important to allow for eventualities.If the recruitment process involves working with teams, you should communicate the recruitment plan before its execution so as to allow for adjustments to be made and synchronizing of the different schedules.The unit manager should approve of the recruitment plan in order to allow for funds to be released for its implementation.Common mistakes in recruitment planningFixing rigid timeframes when planning and hence rushing the interview and other stages in the recruitment process.Use of inefficient advertising methods which translates to fewer candidates being reached.Step 4. Selecting hiring committeeA hiring committee is instituted to protect the selection and hiring process from bias and hence come up with the most suited candidate. It is therefore important that the committee be constituted by staff from across the board and under-represented groups and women are included.The committee should also hav e an individual with a strong understanding of the role and its importance in light of the department’s objectives and if possible with previous experience in the same role. It also should include someone with technical know-how of the job. Lastly, an individual who will be in close contact with the position such as the immediate supervisor.Tips for selecting the hiring committeeEnsure the hiring committee is as diverse as possible. This will bring in different perspectives and a deeper assessment of candidate’s strengths and weaknesses.It is crucial that none of the members of the committee has vested interest in any of the candidates or any other conflicting interests.The hiring committee should be well versed with the recruitment process and are often given brief trainings prior to the interview.Common mistakes in selection of the hiring committeeThe most common mistake is failure to diversify the committee. Often the members selected are from one department and thus are not representative of the entire organization. This limits the assessment of the applicant to only one perspective of his or her suitability for the position.Step 5. Post Job  and Implement Recruitment PlanOnce the job  description had been finalized, the job should then be posted in the predetermined platforms for the set number of days. Once the minimum number of posting days has been reached, applications should then be reviewed by the committee.Companies should use multiple avenues for recruitment in order to widen the pool of candidates reached.Best practices for posting the position and implementing the recruitment planSince the objective is to attract as many qualified people as possible, it is at this point that companies recruit passive candidates.The hiring manager must monitor the progress of the recruitment plan in order to ensure all set goals are achieved.Common mistakes in posting the position and implementing the recruitment planOften there is a lack of continuous monito ring during implementation which backsets the success of the process.Always think about what candidates you are trying to reach: active vs passive job candidates.[slideshare id=34280112doc=kocg10005kgwi12014engagement1-140505024917-phpapp02w=640h=330]Step 6. Review Applicants and Develop Short ListAfter the end of the posting days, the hiring committee then embarks to review all the applications and determine which best meets the required qualifications. It is of importance that each application be reviewed by more than one member of the committee in order to eliminate bias.After making the final review, the committee will then come up with a short list of the best qualified applicants who will then proceed to the interview stage.Tips for reviewing applicants and developing a short listIf the applications received are too many, the hiring committee can work in teams in order to move through them faster.It is important to know the targeted number of interviewees.It is easier to short list candidates using an elimination method.The hiring team must first understand the roles and responsibilities of the position and know the necessary requirements of the job. The chairman of the hiring committee should then again go through the short list to ensure that the selected candidates meet this criterion.Step 7. Conducting Interviews and selecting hiresThis is the most crucial part of the recruitment process. It may involve one or more interview sessions where candidates are subsequently eliminated.The committee may choose to use video interview or in-person or both. It is critical that the team be prepared and have a documented procedure and set of questions based on each section of the position description.Once the interview process is complete, the hiring committee should then use its evaluation tools to come up with a decision as to the best suited candidate after which they will conduct reference checks before making an offer to the successful candidate.Tips and best practices in conducting interviews and selecting hiresPre-screening the selected candidates ensures that only the very best candidates make it for the in-person interview and also saves time.Interview questions should always be objective.Recruiters should look for compatibility of the candidate with the company’s culture.It is important to be consistent with the questions asked.Non-verbal language is just as important in communication and recruiters should pay attention to it.The interview process is also conducted by a panel to eliminate bias.Common mistakes in the interview processFailure of panelists to prepare for the interviewEvaluating candidates on the wrong factorsFACTORS DETERMINING THE RECRUITMENT AND HIRING PROCESSThese are internal and external factors that influence the recruitment and hiring function in an organization; they maybe within or outside of the organization.Internal FactorsThese are also called endogenous factors. They are usually within the organizationâ €™s control, and include:Personnel utilization A company may decide to utilize its employees’ skills set and expertise and thus avoid hiring new personnel. This may be due to a managerial decision to build the capacity of the current workforce and thus enhance efficiency and production.Recruiting policy of the organization A predetermined organization policy may very well dictate whether or not an organization involves itself in the recruitment process. For instance a company’s policy may stipulate internal hiring only or temporal hires. A common example is where most multinational companies have a policy that ensures local hires only for certain positions.Size of the organization Larger organizations tend to recruit more people and therefore as the process is less cumbersome for them due to the structures, personnel and resources at their disposal. The recruitment process is more difficult for the smaller scale organizations as the limited resources are directed towards thei r core business.Cost considerations There are a variety of costs related to recruiting and hiring including advertising costs, consultancy costs, panel remuneration, and time costs. Therefore the costs incurred may deter an organization from hiring more people or affect their strategy. Companies may prefer to hire several positions at one time in order to lower their cost per hire and therefore increase efficiency.Organization’s image A company’s image or brand affects the number of applicants that would be attracted to the positions they offer. An organization with a good brand as an excellent employer will have no problem drawing a large and diverse pool of talent. On the other hand, companies known to have undesirable employment history such as low pay will experience a greater difficulty getting the best hires.Rate of growth Organizations that are rapidly expanding their operations tend to recruit new personnel at a faster rate in order to cope with the increasing tasks a nd responsibilities. However, companies with a slower or stagnant growth rate employ at a slower rate and in many cases downsize their labor force.External FactorsSupply and demand The forces of supply and demand in the labor market directly influence the availability of candidates. When there is high supply of labor than the company’s demand, the recruitment process is simpler as the talent pool is flooded. When the supply is lower than demand, employers have a much harder time securing the best candidates and may have to counter with very attractive remuneration packages or sourcing internally.Labor force demographics The population distribution also affects the recruitment process. Currently, most Western countries are experiencing labor shortage due to low population and are seeing older people delaying retirement to fill in the niche. And the trend is expected to continue in coming years as shown below.Labor market When there are high rates of unemployment, organizations a re able to easily recruit as labor is abundant. However when the unemployment rates are low, candidates are harder to find and therefore the recruitment process becomes much more difficult and costly.Legal and political frameworks The recruitment and hiring process is regulated by laws and policies that often dictate their choice of hire. Anti-discrimination laws have ensured the inclusion of previously discriminated and underrepresented persons in companies’ recruitment.CHALLENGES FACED IN A RECRUITMENT AND HIRING PROCESS AND HOW TO OVERCOME THEMLabor market competition due to an influx of recruitersRecruiting firms have swarmed the market and with this turn there are many options open to the candidate. It is therefore harder for companies to attract and secure the best fit for their positions.The company should therefore look to expand their recruiting sources through social and professional networking, advertising, referral programs, campus recruitment and recruitment of “pa ssive” employees.Multiple offers to the best candidatesThe best candidates often have a number of job offers within their reach and many companies lack the tact and skill to win them over. An organization should improve its candidates’ experience in order to counter this.This can be done through having a pre-selection interaction, where the applicant can have access to the company’s information such as company’s corporate culture, mission, social corporate activities, et cetera.It is also important to provide prompt feedback throughout the recruitment process to the candidate so as to build confidence.Technology gapMany hiring managers are not conversant with modern technology and often use outdated recruitment strategies that do not resonate with generation Y preferences nor meet their expectations. As such, these recruiters have a harder task getting the right people for the job.The hiring managers should research on the most appropriate and current technologies in order t o keep abreast with emerging trends and attract a wider pool of the tech-savvy workforce.High labor turnoverThis is in part due to preference of adventure over security for most of the current candidates with many of them looking for more challenging opportunities. It is therefore much more difficult today for employers to retain their workers. This however need not remain a challenge.The management should ensure constant evaluation of the performance and satisfaction of its employees and create more challenging opportunities for the deserving to advance their careers. This will also give insight on any factor within the workplace that is hindering optimum production.Financial constrainsMany companies are feeling the effects of the economic recession. Human resources have not been left out with many departments getting sliced budgets. It is therefore important that recruiters find cost effective ways to hiring new talent.One of those options has been to outsource, which does signifi cantly reduce operational costs, but companies can also optimize modern technology to hire at much lower costs.Candidates dropping outThis happens when a candidate after going through the entire recruitment process, backs out before accepting the offer. It results in lost time as well as resources as hiring managers have to begin their search again.These incidences may be significantly reduced by maintaining communication with the candidates during the recruitment process and encouraging feedback, as well as utilizing recruitment metrics such as quality of hire.CONCLUSIONThe task of selecting the perfect candidate may seem daunting to many, what with the ever changing market trends, candidates with diverse social-cultural orientations, restrictive timelines and budgets. This guide is designed help you navigate the recruitment and hiring process much more easily and point out the ways you can optimize this process and turn it into an enjoyable and beneficial experience for your organ ization as well as for your potential employees.With the highlights on the emerging recruitment trends, you shall be a step ahead of the competition in the recruitment game, optimizing the cost efficient and time-saving technologies that generation Y are accustomed to.The step by step outline of the process and common mistakes employers make will enable you to keep off the often times costly landmines as well as have a firm grasp of what the process entails.

What Is the Great Sphinx - Brief Overview

Question: What Is the Great Sphinx? Answer: The Great Sphinx  is a massive statue with the body of a lion and the face of a man. Dont get worried if you mix this one up with the Greek monster that riddled Oedipus at Thebes - they share the same name and are both mythical beasts that are part-lion. Just how big is the Sphinx? It measures 73.5 m. in length by 20 m. in height. In fact, the Great Sphinx is the earliest known monumental sculpture, although the statue has been missing its nose since at least Napoleonic times. It resides on the  plateau of Giza, where the most famous - and biggest - of the  Old Kingdom  pyramids are located. The  Egyptian necropolis at Giza contains three monumental pyramids: the Great Pyramid of  Khufu (Cheops),who may have ruled from about 2589 to 2566 B.C.,the Pyramid of Khufus son,  Khafra (Chephren),who may have ruled from about 2558 B.C. to about 2532 B.C.,  the pyramid of Khufus grandson,  Menkaure (Mycerinus). The Sphinx was probably modeled after - and built by - one of these pharaohs. Modern scholars think that guy was Khafre - although some disagree - meaning the Sphinx was built in the twenty-sixth century B.C. (although some archaeologists maintain otherwise). Khafre probably modeled the Sphinx after himself, meaning that famous head represents this O.G. pharaoh. What was the point of a king showing himself as a half-lion, half-human mythical creature, especially if hed already built a pyramid to commemorate his life? Well, for one, having a giant god version of yourself watching over your pyramid and temple for eternity is a pretty good way to keep tomb robbers away and impress future generations, at least in theory. He could watch over his tomb complex forever! The Sphinx was a special creature whose crafting showed how the man he represented was both royal and divine. Both lion and man, he wore the  names  headdress of the pharaoh and the long false beard that only a king wore. This was the representation of a god king above and beyond his usual depiction, a creature beyond normal comprehension. Even in antiquity, the Egyptians themselves were fascinated by the Sphinx. The pharaoh Thutmose IV - who hailed from the Eighteenth Dynasty and ruled in the late fifteenth and early fourteenth centuries B.C.   - set up a stele between its paws that declared how the statues spirit came to him in a dream and promised to make him king in exchange for the young mans dusting the Sphinx off. This proclamation, a.k.a. the Dream Stele, records how Thutmose took a nap near the Sphinx, who popped up in his dream and made him the bargain if Thut got rid of the sand burying him.

Code Division Multiple Access Communication Systems Free Essays

string(31) " be noise like to other users\." Chapter 2- Communication System Telecommunication systems have now made it possible to pass on with virtually anyone at any clip. Early telegraph and telephone system used Cu wire to transport signal over the earth’ surface and across oceans and high frequence ( HF ) wireless, besides normally called shortwave wireless, made possible inter-continental telephone links.Every communicating system has its ain frequence scope, system, capacity, application execution cost. We will write a custom essay sample on Code Division Multiple Access Communication Systems or any similar topic only for you Order Now On the footing of transmittal system there are two types of communicating system †¢ Wired communicating system †¢ Wireless communicating system 2.2 Multiple Access Technique A limited sum of bandwidth is allocated for radio services. A radio system is required to incorporate as many users as possible by efficaciously sharing the limited bandwidth. Therefore, in communicating, the term multiple entree can non be defined as a agency of leting multiple users to at the same time portion the finite bandwidth with least possible debasement in the public presentation of the system. There are four multiple entree methods – a ) Frequency Division Multiple Access ( FDMA ) B ) Time Division Multiple Access ( TDMA ) degree Celsius ) Code Division Multiple Access ( CDMA ) vitamin D ) Space Division Multiple Access ( SDMA ) Frequency Division Multiple Accesses ( FDMA ) FDMA is one of the oldest multiple entree techniques for cellular systems when uninterrupted transmittal is required for parallel services. In this bandwidth is divided into a figure of channels and distributed among users with a finite part of bandwidth for lasting usage, as illustrated in figure 2.2. The channels are assigned merely when there is a demand of the users. Therefore when a channel is non in usage it consequences in a otiose resource. img alt="" src=""/ Fig 2.2Channel Use by FDMA FDMA channels have narrow bandwidth of about 30 KHz, and therefore they are normally implemented in narrow set system. Since the user has his part of bandwidth all the clip, FDMA does non necessitate clocking control, which makes it simple. Even though no two users use the same frequence set at the same clip, guard sets are introduced between sets to minimise channel intervention. Guard sets are fresh frequence slots which separates neighbouring channels. This leads to a wastage of bandwidth. In a non-continuous transmittal bandwidth goes wasted since it is non being utilized for a part of the clip. Time Division Multiple Access ( TDMA ) In digital systems, uninterrupted transmittal is non required as the users do non use the allotted bandwidth all the clip. In such systems, TDMA is a technique compared to FDMA. Global Systems for Mobile communications i.e GSM uses the TDMA technique. In TDMA, bandwidth is available to the user but merely for a finite period of clip. In most instances the bandwidth is divided into fewer channels compared to FDMA and the users are allotted clip slots during which they have the full channel bandwidth at their disposal. This is illustrated in figure 2.3. img alt="" src=""/ Fig 2.3Channel Uses by TDMA TDMA requires careful clip synchronism since users portion the bandwidth in the frequence sphere. As the figure of channels are less, channel intervention is about negligible, hence the guard clip between the channels is significantly smaller. Guard clip is spacing clip between the TDMA. In cellular communications, whenever a user moves from one cell to other there is a opportunity that user could see a call loss if there are no free clip slots. TDMA uses different clip slots for transmittal every bit good as response. Code Division Multiple Access In CDMA, all the users occupy the same bandwidth, though they are all assigned separate codifications, which distinguishes them from each other as shown in figure 2.4. CDMA systems utilize a spread spectrum technique in which a spreading signal, is uncorrelated to the signal and has a larger bandwidth, is used to distribute the narrow set signal. Direct Sequence Spread Spectrum i.e DS-SS is most normally used for codification division multiple surplus. In Direct sequence spread spectrum, the message signal is multiplied by a Pseudo Random Noise Code, which has a noise like belongingss. Each user has its ain codification which is extraneous to the codification of every other users. In order to feel the user, the receiving system is required to cognize the codeword used by the sender. contrasting TDMA, CDMA does non necessitate clip synchronism between the users. img alt="" src=""/ Fig 2.4Channel Uses by CDMA 2.4 CDMA 2.4.1 History Code Division Multiple Access ( CDMA ) is a new construct in wireless communications. It has achieved widespread credence by cellular system operators, that will dramatically increase both their system capacity and the service quality. CDMA is a signifier of spread-spectrum, that have been used in military applications for old ages. The rule of spread spectrum is the usage of noise-like moving ridges and, as the name connote bandwidths much larger than that required for simple point to indicate communicating at the same information rate. foremost there were two motive: To defy enemy attempts to throng the communications ( anti-jam, or AJ ) , or to conceal the fact that communicating was even taking topographic point, from clip to clip called low chance of intercept. It has a history that goes back to the early yearss of World War second. The usage of CDMA for nomadic wireless applications is new. It was planned theoretically in the late fourty’s. profitable applications became promising because of two evolutionary developments. One was the handiness of really low cost, high denseness digital ICs, which cut down the size and cost of the endorser Stationss to an adequately low value. Introduction to CDMA CDMA is a multiple entree technique that allows multiple users to convey independent information within the same bandwidth at the same time. Each user is assigned a pseudo-random codification that is either extraneous to the codifications of all the other users or the codification possesses appropriate cross-correlation belongingss that minimize the multiple entree intervention ( MAI ) . This codification is superimposed on an information signal therefore, doing the signal emerges to be noise like to other users. You read "Code Division Multiple Access Communication Systems" in category "Essay examples" Merely the intended receiving system has a reproduction of the same codification and uses it to pull out the information signal. This so allows the sharing of the same spectrum by multiple users without doing inordinate MAI. It besides ensures message privateness, since merely the intended user is able to â€Å"decode† the signal. This codification is besides known as a spreadi ng codification, since it spreads the bandwidth of the original informations signal into a much higher bandwidth before transmittal. 2.4.2 CDMA Classification Tree img alt="UntitledFEDF.png" src=""/ Fig 2.6Classification Tree of the assorted types of CDMA Techniques Advantages of CDMA One of the chief advantages of CDMA is that call dropouts occur merely when the phone is at least twice every bit far from the base station. It is used in the pastoral countries where GSM make non acquire to work decently. Another advantage is capacity means it has a really high spectral capacity so that it can suit more users. Disadvantages of CDMA One major job in CDMA engineering is channel pollution, where signals from excessively different cell sites are present in the subscriber’s phone but none of them is foremost. When this state of affairs arises the characteristic of the audio signal degrades. Another disadvantage is when compared to GSM it lacks international roaming capablenesss. 2.5 Spread Spectrum Spread spectrum are the methods in which energy generated at a individual frequence is spread over a broad set of frequences. The basic spread spectrum technique is shown in Figure 2.7. This is done to accomplish transmittal that is robust against the channel damages, and to be able to defy natural interventions or thronging besides to forestall hostile sensing. These techniques were developed by military counsel systems. The technique is said to be spread spectrum if transmittal bandwidth is much greater than minimal bandwidth needed to convey the information.The system achieves spread spectrum if it fulfills the undermentioned demands: Signal occupies bandwidth much larger of the minimal bandwidth necessary to direct information. Spreading is done with the aid of distributing codification signal which is independent of the informations. At the receiving system, de-spreading is done by the correlativity of the received dispersed signal with a synchronised reproduction of the distributing signal used to distribute the information. img alt="" src=""img alt="" src=""Spread signal bandwidth img alt="" src=""img alt="" src=""Undesired signal img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""informations signal img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""recovered informations Spreading code signal Spreading codification signal Fig 2.7Model of Basic Spread Spectrum Technique The chief parametric quantity in dispersed spectrum systems is the treating addition: Is the ratio of transmittal and information bandwidth:Gp =img alt="" src="", which is fundamentally the spreading factor. The processing addition calculates the figure of users that can be allowed, the sum of multi-path effects and the trouble to throng a signal. Spread spectrum can be classified as follows – a ) Direct Sequence Spread Spectrum B ) Frequency Hoping Spread Spectrum degree Celsius ) Time Hopping Spread Spectrum 2.5.1 DS-CDMA Direct Sequence is the best Dispersed Spectrum Technique. The DS-CDMA method provides a multiple of benefits in cellular systems including easiness in planing frequence channels and protection against intervention, such that a high procedure addition is used. In DS-CDMA each user has its ain spreading codification. The choice of good codification is of import because auto-correlation belongingss and length of the codification restricts system capacity. The codification can be divided into two categories- Orthogonal codifications ( Walsh codifications ) Non-orthogonal codifications ( PN, Gold, Kasami codifications ) The informations signal is multiplied by a Pseudo Random Noise Code. A PN codification is a sequence of french friess its scope is -1 and 1 ( polar ) or 0 and 1 ( non-polar ) . This consequences in low cross-correlation values among the codifications and the trouble to throng or observe a information message. A usual manner to make a PN codification is by agencies of at least one displacement registry. The bit rate decides the rate at which distributing signals are transmitted. At the receiver terminal, spread signals are decoded with the aid of correlativity maps. Cross correlativity de-spreads the standard signals and retrieves the familial signal similar to the user’s original signal. The distributing sequences can orthogonal agencies ‘0’ transverse correlativity or random sequences with low cross-correlation belongingss. img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""Y ( T )img alt="" src=""/ img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""m ( T ) C ( T ) Cos ( wt ) Fig 2.8Direct Sequence Spread – Spectrum Modulation System In the DS-CDMA technique, each spots of the users informations are multiplied with a codification in the transmitting terminal. The codification sequence used in conveying terminal performs the function of distributing codification. The baseband theoretical account of a DS-CDMA system is shown in fig 2.8. Let m ( T ) denotes a binary information sequence, degree Celsius ( T ) denotes a codification sequence. The wave forms m ( T ) and c ( T ) denote polar representations in footings of two degrees as  ±1. By multiplying the information spots by the codification, each information spot is divided into a little clip increases that are called french friess.

By multiplying each spot with a PN codification, users spots are represented by seven french friess as shown above. User 1 [ 1 ] : 1 C1: -1 -1 1 1 1 -1 1 = A ; gt ; -1 -1 1 1 1 -1 1 User 2 [ 1 ] : -1 C2: 1 -1 -1 1 1 1 -1= A ; gt ;-1 1 1 -1 -1 -1 1 User 3 [ 1 ] : 1 C3: -1 1 -1 -1 1 1 1 = A ; gt ; -1 1 -1 -1 1 1 1 User 4 [ 1 ] : -1 C4: 1 -1 1 -1 -1 1 1= A ; gt ; -1 1 -1 1 1 -1 – 1 R [ 1 ] : -4 2 0 0 2 -2 2 ( received informations ) The received information consists of information of four users. To retrieve the original spots of users from the received informations, the received informations should multiplied with the codification sequence in the receiving system that is precisely same with that is used for distributing the original informations in sender agencies ( de-spreading ) . We assume that the receiving system operates in perfect synchrony with the sender. As a last measure, determination is made by comparing the consequences with a threshold value as shown below. R [ 1 ] * C1= 4-2+2+2+2= 8 A ; gt ; 0 = A ; gt ; 1 R [ 1 ] * C2= -4-2+2-2-2= -8 A ; lt ; 0 = A ; gt ; -1 R [ 1 ] * C3= 4+2+2-2+2= 8 A ; gt ; 0 = A ; gt ; 1 R [ 1 ] * C4= -4-2-2-2+2= -8 A ; lt ; 0 = A ; gt ; -1 Advantages of DS-CDMA It has an intervention rejection belongings ; every user is identified with a specific codification sequence which is about extraneous to the other users codifications. The DS-CDMA besides excludes the demand of channel spliting therefore all users use the full channel bandwidth. Furthermore, it is stiff to multipath attenuation. Signals in DS-CDMA systems are indistinguishable strength full a broad bandwidth which can pull strings the multipath attenuation to modify the end product. Properties of DS-CDMA. Multiple Access – If multiple users use the channel at the same clip, there will be multiple signals overlapping in clip and frequence. At the receiver terminal coherent demodulation is used to take the codification transition. This method concentrates the power of the desired user in the information bandwidth. If the cross-correlations between the codification of the desired user and the codifications of the interfering users are little, consistent sensing will merely set a little portion of the power of the interfering signals into the information bandwidth. Narrowband Interference- The coherent sensing at the receiving system involves a generation of the standard signal with a locally generated codification sequence. However, as we see at the sender, multiplying a narrowband signal with a wideband codification sequence spreads the spectrum of the narrowband signal so that its power in the information bandwidth decreases by a factor which is equal to the processing addition. 2.6 Problem Description Main job with DS-SS is the so called Near –Far consequence. This is described by an illustration. In figure 2.12 this consequence is present when an interfering sender TX ( B ) is closer to the receiving system RX ( A ) than the intended TX ( A ) and, the correlativity between the standard signal from the interfering sender TX ( B ) and RX ( A ) can be higher than the correlativity between the standard signal from the intended sender TX ( A ) and RX ( A ) . The consequence is that proper informations sensing is non possible.

Hidden terminusjob refers- The hit of package at the having node due to the coincident transmittal of those nodes that are non within the direct transmittal scope of the transmitter. Exposed terminusjob refers- The inability of a node which is blocked due to nearby transmission node, to convey another node. For Example if both node S1 and S2 transmit to node R1 at same clip their packages collide at node R1.This happens because both nodes S1 and S2 are hidden from each other as they are non within the direct transmittal scope of each other. This is called concealed terminus job. On the other manus if a transmittal from node S1 to another node R1 is already in advancement, node S3 can non convey to node R2, as it concludes that its neighbour node S1 is in conveying node and hence it should non interface with the on-going transmittal. This job reduces the throughput of web when traffic burden is high. img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="" src=""img alt="Untitled.png" src=""/ Transmission scope of node S1 Transmission scope of node S2 img alt="" src=""/ Fig 2.13Hidden and Exposed Terminal Problems 2.7 Proposed Work The Basic motivation of our undertaking was to analyze and develop an Efficient Mac based DS-CDMA protocol for work outing near far job. A CDMA communicating system requires an efficient design and testing of its subsystems of PN-sequence generator, spectrum spreading and de-spreading digital circuits and digital modulator and detector faculties which give high throughput. Another issue is near far consequence. 2.7.1 Reason for proposed protocol The Near far consequence is created in the uplink of DS-SS CDMA. When a combination of unfastened and closed-loop power control which ensures that each terminus generates the same signal power at the base station. The base station monitors the power of standard signal from each terminus and instructs distant terminuss to increase their signal powers and nearby terminuss to diminish theirs illustration below shows the power control entirely is non plenty to cut down the near–far job in DS SS CDMA ad-hoc Network. Example: – Letimg alt="" src=""denote the distance between nodes Ks and n. suppose A wants to pass on with B utilizing a given codification and C wants to pass on with D utilizing a different codification. Suppose that tap ? dCD, dCB A ; lt ; A ; lt ; tap, and dad A ; lt ; A ; lt ; dCD. Then, the MAI caused by C makes it impossible for B to have A transmittal. Similarly, the Multiple entree intervention caused by A makes it impossible for D to have C transmittal. It is of import to observe that the two transmittals can non take topographic point at the same time, irrespective of what transmittal powers are selected if an addition in power is made to battle the MAI at B, this increased power will destruct the response at D. img alt="" src=""/ Fig 2.14Example shows the Power Control entirely is non plenty to cut down the Near–Far job in DS-SS CDMA Ad-hoc Network The above Fig. unveils two types of jobs – . 1.Medium entree job: – The usage of two different distributing codifications to happen at the same clip is non possible for two transmittals, this job is referred to as medium entree job. 2. Power control job: – If the terminuss adjust their signal powers so two transmittals can take topographic point at the same clip so that the intervention caused by one transmittal is non big plenty to pulverize package response at other terminuss. This is referred as power control job. So the cardinal solution to the close far job must hold both elements: power control and medium entree. 2.7.2 DESIGN GOAL FOR PROTOCOL The Following are the specifications while planing a MAC protocol for Ad-hoc web: The operation of the protocol should be widen and provide quality of service for existent clip traffic. The protocol must be a non-synchronous, spread operation, every bit good as scalable for big webs. It must besides affect minimum exchange of information and must be suited for real-time execution. The protocol must be scalable to big web. in this protocol should be minimise the consequence of hidden and exposed terminus job. The protocol should hold agencies for adaptative informations rate control and it should hold power control mechanisms in order to expeditiously pull off the energy ingestion of node. The receiving system circuitry should non be complex in the sense that it should non be required to supervise the whole codification set. So we design the DS-SS CDMA system with MAC protocol utilizing VHDL.
