摘　　要：论文给出了MIMO系统采用极化分集时的信道模型,对接收信号空间相关性和信道容量进行了研究,并对其随接收天线极化夹角的变化情况进行了分析。研究表明,采用极化分集技术的MIMO系统具有良好的非相关衰落特性,信道容量得到显著提高。In this paper, a MIMO channel model in the presence of polarization diversity is presented, the spatial correlation between signals and the channel capacity is analyzed, and the effect of polarization angle between receiving antennas on the spatial correlation and the channel capacity is investigated. Simulation results show that MIMO wireless system using polarization diversity is of excellent fading characteristic, and channel capacity is increased effectively.
