摘要: 针对平坦衰落环境中的极化分集MIMO信道,建立了三维空间中的接收信道模型,推导出了关于水平角度扩展和俯仰角扩展的相关函数表达式,分析了水平角度扩展和俯仰角扩展对信道相关性的影响,并且仿真分析了角度扩展对信道容量的影响。

Abstract: This paper proposes a 3D statistical polarized MIMO channel model for the mobile frequency nonselective fading MIMO channels.Two general correlation coefficient expressions about AOA and EOA using a statistical model of incident waves are derived.Furthermore,the effects of correlation coefficient and channel capacity are given by computer simulation.
