| 摘 要： | 对未知信道状态和已知信道状态下的莱斯信道多天线系统容量进行了理论分析，并采用蒙特卡罗方法进行了仿真，结果表明：在低信噪比情况下，当天线数目较小、视距分量较少；或者天线数目较大、视距分量较多时，采用传输功率优化策略较为合理。

| Abstract: | This paper analyzed the capacity of the Ricean MIMO channel by the unknown and known channel information respectively and discussed the simulation result. It showed that in the case of low SNR, when the number of the antennas and LOS component ratio were small or large, it was reasonable to adopt the optimized power allotment. |

| Keywords: | transmission optimized power allotment Ricean channel multi-antenna system capacity |
