Abstract

In this paper, a non-data aided minimum mean square error (MMSE) receiver with enhanced multiple access interference (MAI) suppressed is proposed over a multipath fading channel. Performance analysis of the output signal-to-noise-plus-interference (SINR) is done to examine the efficacy of the proposed receiver, which can offer the same results as that of the optimal MMSE receiver with the channel estimation correctly obtained beforehand. Computer simulation results then confirm the correctness of the analysis results and demonstrate that the proposed blind receiver can effectively resist MAI as well as the finite data sample effect
