ABSTRACT

 

As the use of mobile communications systems grows, the need arises for new and more efficient channel allocation techniques. In the proposed paper I wish to discuss and analyze different channel allocation techniques. Many factors have effects on channel assignments such as modulation techniques, handoff procedure, minimum S/N ratio requirement and bandwidth size (PCs network need far bigger bandwidth in comparison to regular CDMA/TDMA/GSM voice call channels). Different types of channel allocation techniques also exist in current market and can be considered for future growth. Main concern of this paper will be to discuss higher bandwidth application concerning CDMA and PCS networks. I believe that video and higher data are going to be used more frequently in coming years as medium to communicate through mobile phones. During paper there will be discussion on different types of channel allocation techniques and comparison will be done among them with emphasize on Dynamic Channel Allocation techniques. I wish to carry out series of simulations to further analyze the theory of allocation techniques in different environments. These simulations and comparison will be done with keeping in mind factors such as S/N ratios, queuing, handoff, blocking of calls, Erlang formula, priority users, mobility of mobile phone, and reuse of channels.
