摘　　要：针对空间相关信道下信号检测误码率性能下降的问题,提出一种多天线分集接收方法。该方法通过增加接收机天线个数,减小信道空间相关性对信号检测的影响,可根据实际工程需求灵活配置相应的接收天线数量,在避免引入高复杂度检测算法的同时具有较优的检测误码率性能。采用等增益合并方式对所提方法进行仿真分析,仿真结果验证了方法的有效性。In response to the issue of performance degradation in signal detection bit error rate under spatially correlated channels,a method of multi-antenna diversity reception is proposed.This method reduces the impact of channel spatial correlation on signal detection by increasing the number of receiving antennas,and can flexibly configure the corresponding number of receiving antennas according to actual engineering needs.While avoiding the introduction of high-complexity detection algorithms,it offers superior performance in detection bit error rate.Simulation analysis is conducted on the proposed method using equal gain combining,and the simulation results confirm the effectiveness of the method.
