Abstract: Multiuser signals detection for CDMA on Rayleigh fading channels is considered.The model multiuser detector is analyzed, and a novel near-optimal multiuser detector proposed. It is showed that bit error rate of this near-optimal detectorhas an advantage over one of conventional detector. With enhancing the number of diversity,its performance is improved.

Key words: CDMA, multiuser detection, Rayleigh fading
