循环延迟分集在相关MIMO信道下的性能
Performance of cyclic delay diversity in correlation MIMO channel
本文给出了编码OFDM系统中接收天线衰落相关性对循环延迟分集(CDD)性能的影响,仿真对比了不同相关系数下的性能。仿真结果表明,当接收天线相互独立衰落时,循环延迟分集可获得最大的分集增益。随着接收天线相关系数增大,分集增益逐渐丧失。
he influence of the fading correlation among receive antennas on cyclic delay diversity(CDD) in coded MIMO-OFDM system is considered. The performance under different correlation coefficient is compared by simulation. Numerical results demonstrate that full space diversity can be obtained when fading among receive antennas are uncorrelated, and the diversity gain will be lost gradually as the increasing of the correlation coefficient.
