摘要:

为了探讨Nakagami m 衰落信道下反馈比特数、接收天线数与系统性能之间的联系,为实际系统应用提供理论依据,针对多个发送天线单个接收天线(MISO)系统,分析了采用随机向量量化(RVQ)有限反馈波束成形时系统的性能,推导出了平均比特错误概率和中断概率闭式解,并将得到的闭式解扩展到基于接收天线选择的多输入多输出(MIMO)系统.仿真结果表明,获得的平均比特错误概率和中断概率闭式解的理论值与实际系统仿真结果一致,验证了所得结果的正确性.

关键词: 有限反馈, 多输入多输出, 随机向量量化, 天线选择, Nakagami m 衰落信道

Abstract:

System performance is studied when employing random vector quantization (RVQ) to qualify limited feedback beam forming for multiple input single output (MISO)system under Nakagami m fading channel, and the closed form of bit error rate and outage probability are derived. The closed form is expanded to the multiple input multiple output (MIMO) system based on receiving antenna selection mechanism. Simulation shows that the results from proposed closed form are consistent with the results of actual system. It verifies that the closed form is correct.

Key words: limited feedback; multiple input multiple output;random vector quantization;antenna selection, Nakagami m fanding channel
