Abstract :
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 compare the performance of this multiuser receiver conjugated with traditional differential detection, multiple symbol detection, Viterbi differential decoding, and multiple phase shift differential detection
