摘要

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.

Abstract

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 (CSI) 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 Frobenius-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 Frobenius-2 norm of received signal vector

the same diversity gain can be achieved as the one obtained by using all the receive antennas.
