Abstract: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.
