Multiuser Receiver with Multi-path Diversity for DS/CDMA Systems

초록

Several multiuser detectors have been recently proposed to multiple-access interference and near-far problem for CDMA multiuser detectors, exploiting knowledge of other users to cancel multiple-access interference, have the potential to provide a significant in capacity of CDMA systems.In this paper, we propose a suboptimal multiuser receiver that combines multipath diversity reception, multiuser detection and decision-feedback .Also, the performance analysis of the proposed multiuser error is derived for frequency selective Rayleigh fading channels. Results show that the proposed receiver provides a significantly performance.
