摘要
为提高多输入多输出(MIMO)无线通信系统的性能,建立了基于标量传感器的均匀矩形天线阵列(URA),并将电磁矢量传感器信号处理方式与MIMO信号处理方式有机结合,建立了基于电磁矢量传感器的天线阵列。推导了各天线阵列的空间衰落相关性公式,分析了方位角和仰角的平均到达及角度扩展等参数变化对于相关性的影响。确立了MIMO系统发射和接收两端的相关性协方差矩阵,分析了不同天线阵列的信道容量大小。通过仿真模拟,证明了电磁矢量传感器阵列具有优异的性能和良好的应用前景。
For the sake of a better performance of multiple input multiple output （MIMO） wireless communication system, a uniform rectangular array based on scalar sensor is developed, and electromagnetic vector sensor（EVS） signal processing method is introduced to the traditional MIMO signal processing method to build up a antenna array based on EVS. Each antenna array＇s spatial fading correlation（SFC） closed-form expression is derived to analyze the influence of different angle parameters. Correlation covariance matrixes of both transmitting and receiving terminals are established for analysis of channel capacity of different antenna arrays. By simulating, it＇s proved that antenna arrays based on EVS have a better nerformance as well as application prospect.
