In this paper the performance analysis of lowcomplexity decorrelating detectors will be presented for both coherent and differentially coherent transmission over the multiple-access, frequencynonselective Rayleigh fading channel. While it is known that correlation-type receivers are near-far limited in the case when a single fading path dominates, it is shown that the aforementioned multiuser detectors eliminate the bit error rate floor, alleviate the near-far problem, and rival optimum demodulation for isolated transmission. The results herein apply to wideband and narrowband CDMA systems.
