| 摘 要： | 基于3维环境的空间统计信道,提出MIMO天线阵列下的VMF分布模型.研究MIMO多天线ULA,UYA和UCA在移动台和基站的拓扑结构,得到VMF(Von Mises Fisher)分布模型下ULA,UYA和UCA的空间衰落相关性(SFC)函数的表达式,比较不同天线阵列对平均仰角(MEOA)的灵敏度.研究表明,MIMO天线阵列的SFC由集中参数、平均方位角(MAOA)及平均仰角(MEOA)决定,该模型的信道性能结果与理论一致.

| Abstract: | In this paper we proposed a Von Mises Fisher (VMF) distribution model for statistical channel model of three-dimensional (3D) in multi antenna array environment.It presented the topology of three antenna arrays,uniform linear array (ULA),uniform Yshaped array (UYA) and uniform circular array (UCA) respectively,for multiple-input and multiple-output (MIMO) antenna systems,and the expression of spatial fading correlatio n(SFC) function for several antenna arrays,namely,ULA,UYA,UCA,was derived in VMF distribution model environment.Different antenna arrays had different sensitivity of mean of elevation (MEOA) and they were analyzed in this paper.The study showed that the SFC of MIMO antenna arrays were dependent on three parameters,namely,concentration parameter,mean azimuth of arrival (MAOA) and MEOA,and the performance of VMF distribution channel was agreed with theoretical calculations. |
