| 摘 要： | 针对矿井巷道,给出了一种MIMO相关性信道的建模方法.该方法利用电磁渡在巷道内传播的冲击响应,得到单输入单输出系统的频率响应,从而扩展得到多输入多输出频率响应矩阵;结合相关函数的定义,计算出相关系数;构建出MIMO系统多天线之间的空间相关矩阵;生成MIMO信道的相关矩阵.通过MATLAB仿真,将相关信道和瑞利信道的容量累计概率分布对比,证明了相关性的存在降低了信道的容量,增加天线数目和间距可以降低相关系数,增加信道容量.

| Abstract: | According to mine tunnel,a new modeling method of MIMO correlated channel was introduced.In this method,by shock response of electromagnetic wave spreaded in the roadway,got the frequency response of single-input single-output system and the frequency response matrix of multiple-input multiple-output system;with the definition of correlation function,correlation coefficient was calculated;constructed the spatially correlation matrix between the multi-antenna of MIMO system;the MIMO correlated was generated.... |
