Eng.) - Asian Institute of Technology, 1997  aIn the mobile radio communication system, the distribution of the number of multipath,  the distribution of amplitude and distribution of phase are varying with terrain and manmade  environment. So, the different types of mobile radio channel are modeled for different  environment. This research study concentrates on a channel model with exponentially  decaying power delay profile. The channel model is modeled as a fortyone rays model. The  delay spread of the channel is changed by changing the decaying factor of the power delay  profile. The range of delay spread considered in this study is zero to two symbols period. The  North American TDMA Digital Cellular Mobile System (IS-54) parameters are used for  simulation study. Simulation results are presented for different types of receiver, Symbol-by Symbol Detector, Decision Feedback Equalizer and Maximum Likelihood sequence  Estimator. The performance of these receivers is investigated by evaluating bit error rate  (BER) as a function of delay spread. 0aMobile communication systems1 aMakelainen, Kimmo,eChairperson1 aSharma, A.B.,eExamination Committee1 aRajatheva, R.M.A.P,eExamination Committee2 aUCOM,eScholarship donor2 aAsian Institute of Technology.tResearch studies project report ;vno.
