| 摘 要： | 基于发射端天线选择对MIMO系统性能的影响进行研究.首先建立信道模型,然后对采用ZF接收机的情况下误码率性能进行分析,并讨论了天线选择标准.仿真结果表明,不进行天线选择,获得误码率为10-2所需要的信噪比至少为22.5 dB;进行天线选择,获得误码率为10-2所需要的信噪比为18 dB,证明天线选择能改善系统性能.

| Abstract: | Performance for MIMO system with transmit antenna selection is analysed.The channel model is established first,an analytical of SER(symbol error rate) for spatial multiplexing with ZF receiver and a criterion of antenna selection are discussed.Simulations demonstrate that the SNR(signal noise ratio) of the system is about 22.5 dB at SER equals 10-2 without antenna selection.When using antenna selection,the SNR of the system is about 18 dB at SER equals 10-2,so antenna selection could improve the performance of system. |
