摘要

本文提出了一种用于同步CDMA系统的新型多用户检测器。其误码率性能接近最优的MMSE多用户检测器，而复杂度仅随活跃用户数的增加而多项式增加。我们还通过最优的MMSE多用户检测器和去相关器展示了它的复杂性和性能。除了同步AWGN信道情况外，我们还提供了异步情况、瑞利衰落信道情况和频率选择信道情况的机制。

Near optimum low complexity MMSE multi-user detector

In this paper we propose a novel multiuser detector for the synchronous CDMA system. Its BER performance approaches the optimum MMSE multiuser detector while the complexity only polynomially increases to the number of active users. We also demonstrate its complexity and performance against the optimum MMSE multiuser detector and decorrelator. In addition to the synchronous AWGN channel case, we also provide the mechanism for the asynchronous case, Rayleigh fading channel case, and frequency selective channel case.
