| Abstract: | 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. |
