摘　　要：入射及反弹射线法是研究MIMO信道的有效技术。基于入射及反弹射线法对室内环境中的MIMO信道电波传播特性进行研究,在不同粗糙度条件下,针对接收功率、均方根时延扩展、MIMO系统信道容量的分布情况及其特点进行了比较分析。仿真结果与文献已知结论一致性良好。Shooting and Bouncing Rays （SBR） is an effective method to investigate multiple-input multi- ple-output （MIMO） channels. The SBR method is chosen to investigate the characteristics of radio wave propagation and MIMO channel capacity in a complex indoor environment. On the condition of different roughness, the distribution of received power, RMS-delay spread and channel capacity of MIMO systems have been predicted and analyzed. Simulation and verification indicate that the results are well corre- spond to the reported conclusions.
