This paper examines the performance achieved in AWGN channels and flat Rayleigh fading channels by combining non-coherent multistage parallel interference cancellation with multiple symbol differential detection algorithms for DS/SS CDMA systems using DBPSK and DQPSK modulation. We are comparing the performance of this multiuser receiver conjugated with the traditional differential detection, multiple symbol detection, Viterbi differential decoding, and multiple phase shift differential detection.
