MIMO无线随机信道模型的仿真

Simulation of A Stochastic MIMO Radio Channel

对多天线技术的信道特征进行分析,并用Matlab仿真了一种随机信道模型。该信道模型不但描述了接收信号的功率分布和多普勒频移,还体现了信道衰落系数之间的相关性,而这种相关性体现了不同环境的特性并和天线结构相关。将仿真结果与Shannon理论的MIMO信道容量作比较和分析,验证了信道模型的正确性。

Theoretical and experimental studies of multiple-input/multiple-output （MIMO） radio channels are presented in this paper. A simple stochastic MIMO model channel has been simulated. This model uses the correlation matrices at the mobile station （MS） and base station （BS） so that results of the numerous single-input/multiple-output studies that have been published in the literature can be used as input parameters. The results of simulation demonstrate that the Shannon capacity of the channel is highly dependent on the considered environments.
