Analysis of LMMSE receivers for WCDMA downlink
Li Zhou · Journal of Chongqing University of Posts and Telecommunications · 2004
Minimum Mean Squared Error (MMSE) criterion can be used to obtain near-far resistant single-user receivers,which can efficiently elimilate MAI and noise in DS-CDMA systems, and the MMSE receiver has become the most practical receiver with promising performance in FRAMES WCDMA downlink. Two LMMSE receivers with different structures are compared in this paper, and adaptive RLS receiver is used for WCDMA downlink in Rayleigh-fading multi-path channels. The simulation results show that adaptive RLS receiver with LMMSE-RAKE structure has an excellent performance even in severe near-far situations.
