摘　　要：针对多天线散射通信系统性能提升,提出一种多天线自适应选频分集方法,并对多天线体制下不同自适应选频分集方法的接收信噪比分布特性进行对比分析。对比分析结果表明,所提出的分集方法的分集性能最优,可应用于多天线散射通信系统。系统误码性能仿真结果也表明,所提出的分集方法的误码性能优于现有的分集方法,可有效提升散射通信系统性能。In order to improve the performance of multi-antenna troposcatter communication system,a multi-antenna adaptive frequency selection diversity method is proposed.By comparing and analyzing the receiving SNR distribution characteristics of different adaptive frequency selection diversity methods under multi-antenna system,the diversity method can obtain the best diversity performance and can be applied to multi-antenna troposcatter communication system.Simulation results show that the performance of the multi-antenna adaptive frequency selection diversity method is better than the existing diversity method and can effectively improve the performance of troposcatter communication system.
