| 摘 要： | 基于早期多径衰落的圆环模型提出一种新的MIMO宏小区窄带信道模型,分析了发送、接收端均为多阵元天线条件下的信道相关特性;通过数学推证得到信道相关函数及相关谱的闭式表达式,提出了在该环境下影响MIMO信道空时相关性的几个主要因素.最后通过仿真结果分析了这些因素对信道相关性的影响.

| Abstract: | In this paper, a new narrow band single bounced channel model in multi input multi output (MIMO) macro cell applications was presented on the basis of multipath fading "one ring" model. The characteristic of channel correlation with multi element antenna arrays both in transmitter and receiver was analyzed.The close form formulae of channel correlation function and cross correlation spectrum were derived. Then, some factors affecting the channel correlation, such as space inter elements of transmitter or receiver, mean angle of arrival, angle spread and Doppler spread were extracted. Some simulations were made to analyze the effect of each factor on channel correlation. |
