摘要 提出了相关多输入多输出信道下的一种空时分组码、空分复用与波束成型相结合的新方案.该方案利用了发射分集和空分复用所带来的分集和复用增益,并基于接收机反馈的信道相关矩阵设计了一种波束成型器.仿真结果表明,这种方案的性能较传统的方案在高信噪比时能获得较大的改善. A new scheme in the correlated MIMO channel consisting of a combination of the space-time block code, the spatial multiplexing and the beamforming is presented. The proposed scheme exploits the benefits of the combining transmit diversity and the spatial multiplexing to provide the diversity and the multiplexing gain. Based on the correlation matrix of the channel, a beamformer is designed. The simulation result shows that this scheme is better in performance than the conventional scheme when the SNR is high.
