本文提出了新的联合线性收发器设计的最小总均方误差（MSE）的标准下，与信道均值，以及在两端的多输入多输出（MIMO）链路的发送和接收相关信息。将接头设计转化为一个优化问题。推导出最佳封闭形式的预编码器和解码器。与信道状态信息（CSI）完全的情况相比，在两端加入线性滤波器，以平衡对信道噪声的抑制和对不完全信道估计噪声的抑制。信道估计误差以及信道相关性对系统性能的影响进行了评估，基于分析和仿真结果。
This paper presents new results on joint linear transceiver design under the minimum total mean-square error (MSE) criterion, with channel mean as well as both transmit and receive correlation information at both ends of a multiple-input multiple-output (MIMO) link. The joint design is formulated into an optimization problem. The optimum closed-form precoder and decoder are derived. Compared to the case with perfect channel state information (CSI), linear filters are added at both ends to balance the suppression of channel noise and the noise from imperfect channel estimation. The impact of channel estimation error as well as channel correlation on system performance is assessed, based on analytical and simulation results.
