large intelligent surface (LIS)-assisted wireless communications have drawn
attention worldwide. With the use of low-cost LIS on building walls, signals
can be reflected by the LIS and sent out along desired directions by
controlling its phases, thereby providing supplementary links fo
研究旨在通过设计最优传输协方差矩阵和对角相移矩阵,来实现下行可配置智能表面辅助的 MIMO 无线通信系统的最大达到遗传率。通过大维度随机矩阵理论的复制方法导出了可达遗传速率的大系统近似,从而可以使用交替优化算法识别渐近优化的传输协方差和对角相移矩阵,该算法可以显著提高可配置智能表面辅助的 MIMO 系统的性能。
