在得到莱斯衰落下正交空时分组码接收信噪比的基础上,分析了在莱斯衰落信道条件下引入正交空时分组码的多天线系统的符号差错性能。理论分析及仿真结果表明在接收天线数量一定的情况下,增加发送天线的数量可以带来更大的分集增益,莱斯系数均值对系统的影响是一致的。
Based on the signal-to-noise ratio of Orthogonal Space-Time Block Code received by Rice Decay, the symbol error performance of multi-antenna system with Orthogonal Space-Time Block Code is introduced under the condition of Rice Fading Channel. Theoretical analysis and simulation results show that with a certain number of receiving antennas, increasing the number of transmitting antennas can bring greater diversity gain, and the influence of the mean of Rice coefficient on the system is consistent.
