摘要 研究了多输入多输出(MIMO)系统Rayleigh衰落信道矩阵的特征值以及天线空间相关性对信道容量的影响。Monte-Carlo数值仿真结果表明:MIMO系统能极大提高Rayleigh衰落环境中的系统容量,且容量随最小收发天线数目的增加而线性增加,但由于相关性对信道矩阵特征值及其统计分布的影响较大,因此可导致MIMO系统容量的损失。 The influence of the matrix eigenvalue in Rayleigh fading channel and antenna space - time correlation on the MIMO capacity is studied. The Monte - Carlo simulation results illustrate that MIMO system may greatly enhance the channel capacity in Rayleigh fading environments, with linearly rising while the minimum number of transmitting and receiving antenna rising, but antenna space - time correlation greatly influences the eigcnvalue and distribution of channel matrix so as to cause the apacity of MIMO system declined.
