中文摘要	为提高准正交空时分组码性能,采用以信噪比最大做为天线选择准则,借助MATLAB对Keyhole信道下的TBH码和Jafarkhani码性能进行仿真,并与瑞利信道下的仿真结果进行比较.结果表明:对于准正交空时分组码系统,由于有匙孔效应,Keyhole信道性能较瑞利信道差很多,而通过天线选择可以提高传输增益,减小误码率.采用接收端、收发两端联合天线选择的方法可显著提高系统性能.; To improve the quasi orthogonal space-time block code(QSTBC) performance,the highest SNR was selected as antenna selection criterion,and the performance simulations of TBH code and Jafarkhani code over Keyhole channel were carried out with MATLAB software,and simulation results were compared with that of Rayleigh channel.Results show that for accurate quasi orthogonal space-time block code system,the performance of the Keyhole channel is poor than that of Rayleigh channel because of the key hole effect.And through the antenna selection,the transmission gain is improved,and the bit error rate is reduced.The method combining the receiving side with antenna selection can improve the performance of the system significantly.; 【作者单位】集美大学信息工程学院；集美大学航海学院；【作者英文名】CHEN Qianga,LIN Zijiea,LIN changchuanb (a.Information Technology College;b.Navigation College,Jimei University,Xiamen 361021,China)
