Precise Error Rate Analysis of Bandlimited BPSK System with Timing Errors and Cochannel Interference Under Generalized Fast Fading Channels

This paper develops an efficient analytical framework for evaluating the average bit-error probability (ABER) of bandlimited coherent binary phase shift keying (BPSK) in generalized fast fading channels, where the fading rate is approximately equal to the symbol rate, subject to timing errors and asynchronous cochannel interferers. Selected simulation and computational results are presented that are of interest for outdoor microcellular and macrocellular system studies. Aside from this, our ABER results also serve as lower performance bounds for practical realizable receivers (where ideal coherent detection is difficult to implement) and as an upper performance bound for bandlimited BPSK in slow fading channels where the fading rates are much slower than the symbol rate.
