摘要

我们考虑了发射机相关和互耦合对MIMO MRC系统的影响。我们提出了三种输入功率指标的最优传输策略以及由此产生的停电概率的公式。数值结果表明,无论功率指标如何,MIMO MRC的大部分性能优势都可以在发射天线间隔接近0.2 - 0.3波长的情况下获得。

The Impact of Mutual Coupling on MIMO Maximum-Ratio Combining
We consider the impact of transmitter correlation and mutual coupling on MIMO MRC systems. We present optimal transmission strategies for three input power metrics as well as formulas for the resulting outage probabilities. Numerical results suggest that, regardless of the power metric, most of the performance benefits of MIMO MRC can be obtained with transmit antennas spaced as close as 0.2 - 0.3 wavelengths.
