摘要

衰落信道和多址干扰的影响限制了WCDMA下行链路系统的性能。本文提出了一种用于下行WCDMA系统的具有空时发射分集的线性最小均方误差多用户接收机。该方案可以有效地抑制信号的衰落效应和多址干扰。在高斯近似下进行了性能分析。仿真结果表明，与传统算法相比，该算法可以获得较大的性能提升。

Space-time transmit diversity with multiple access interference suppression for downlink WCDMA systems

The effects of fading channels and multiple access interference limit the performance of downlink WCDMA systems. In this paper, a linear minimum mean-square error multiuser receiver with space-time transmit diversity is proposed for downlink WCDMA systems. The fading effect and multiple access interference can be jointly mitigated by the proposed scheme. The performance analysis under Gaussian approximation has also been carried out. Simulation results show that substantial performance gain can be achieved compared with conventional algorithms.
