| 摘 要： | 研究了在空域相关条件下MIMO通信系统的信道容量问题，利用Wishart矩阵的联合特征值概率密度函数显式给出了平坦性瑞利衰落信道的各态历经容量的可计算公式，利用Matlab所进行的数值计算表明：与已有的蒙特卡洛方法相比，公式提高了计算速度。数值计算结果还进一步表明了影响空间相关性的天线间距、来波角度和角度扩展这三个参数与信道容量之间的关系。

| Abstract: | The capacity of MIMO communication system under the spatial correlation is investigated. A calculable capacity formula about Flat-Fading Raleigh channel is derived based on the joint eigenvalue probability density function of Wishart matrix. The result obtained by Matlab numeric calculation shows that, compared with the past Monte Carlo method, the method in this paper improves the speed of calculation. The interrelation between the channel capacity and the three parameters which are antenna separation, incoming wave angle and angular spread is also discussed based on the results of numeric calculation. |
