Multiple-input multiple-output (MIMO) is a favorable technique that can improve system capacity and performance through spatial multiplexing. However, the performance gets degraded over the correlated wireless channels. In this letter, we consider a point-to-point MIMO system and jointly optimize both the precoding matrix and the difference between two transmit vectors to resist transmit correlation. The simulation results demonstrate that the proposed method can get average 75% gain comparing with the existing method in terms of the minimum pairwise error probability.

最佳开环 MIMO 预编码器设计


多输入多输出（MIMO）是一种有利的技术，可以通过空间复用来提高系​​统容量和性能。然而，相关无线信道的性能会下降。在这封信中，我们考虑点对点 MIMO 系统，并联合优化预编码矩阵和两个发射向量之间的差值以抵抗发射相关性。仿真结果表明，在最小成对误差概率方面，与现有方法相比，该方法可以获得平均75%的增益。
