非相干天线选择算法

Noncoherent Antenna Selection Algorithem

基于广义似然比检验(GLRT)与天线选择相结合,提出了平瑞利衰落信道的非相干天线选择(NON-AS)算法,天线选择和信号检测无需信道状态信息.NON-AS算法适用于多输入多输出(MIMO)系统的接收端,接收天线选择是基于每个天线瞬时接收到信号矢量的F-2范数.与相干检测的天线选择相比,NON-AS算法不需要估计信道,大大降低了系统复杂性.成对错误概率分析和仿真结果表明:在高信噪比情况下,选择有最大范数的接收天线,系统能实现和使用全部接收天线相同的分集增益.

Based on combining the generalized likelihood ratio test （GLRT） with antenna selection（AS） ,the paper presents a non-coherent antenna selection （NON-AS） algorithm over flat Rayleigh fading channel, which do not require channel state information （CS1） for antenna selection and signal detection. The NON-AS algorithm can be applied to receiver of multiple input and multiple output（MIMO） systems, and selection of receive antennas is based on the Fmbenius-2 norm of instantaneous received signal vector. Compared with coherent antenna selection, the NON-AS algorithm do not require estimating channel state information, which greatly reduce system complexity.The pair-wise error probability analysis and simulation results show that, under the condition of high SNR, by selecting the set of antennas that observe the largest instantaneous Fmbenius-2 norm of received signal vector, the same diversity gain can be achieved as the one obtained by using all the receive antennas.
