520			_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.
