Abstract :
We present a comparison of four of the most discussed multiuser receiver structures: the decorrelator, the minimum mean square error (MMSE) receiver, the multistage parallel interference cancellation receiver, and the successive interference cancellation receiver. Comparisons are based on both theoretical analysis and simulation results. We examine the bit error rate (BER) performance in AWGN, Rayleigh fading, and near/far channels, as well as the computational complexity. Finally, we present results for non-coherent implementations of the aforementioned receivers
