摘要(Abstract)：

电力通信网络的架构及无线信道特性是决定网络性能的关键因素。首先,研究基于南方电网电力无线宽带专网的双层无线接入架构,该架构中宏蜂窝与汇聚网关之间的MIMO信道的性能将直接影响到电网的稳定和运营水平。因此,对MIMO信道性能的研究就尤为重要。主要对MIMO信道的两个典型模型WINNERⅡ模型和Kronecker模型分别从信道空间相关性、信道容量、时域衰落三方面进行理论分析与对比仿真。由仿真结果得到天线数量、信噪比、天线阵列等因素对信道容量和天线相关性的影响。仿真结果说明MIMO技术能够在电网多业务承载环境下,满足系统高速率、大容量的要求。通过比较,WINNERⅡ模型与真实传播环境匹配度高,可在双层无线接入架构中得到进一步的应用。
