摘要 WCDMA下行链路的性能受到信道衰落和多址干扰的影响。本文提出一种带时空编码的WCDMA下行链路MMSE接收机，可以在减小信道衰落的同时达到抑制多址干扰的目的。应用高斯近似法对接收机性能进行了分析。仿真结果表明，该接收机能使系统性能得以较大提高。 The effects of fading channels and multiple access interference limit the performance of downlink WCDMA systems. A minimum mean-square error receiver with space-time coding is proposed for downlink WCDMA systems. The fading effect and multiple access interference can be jointly mitigated. Analysis under Gaussian approximation is also given. Simulation results show that substantial performance gain can be obtained.
