| 摘 要： | 在非协作的通信环境中，由分布式接收天线构成的“虚拟天线阵列”信号模型与常规的盲源分离的典型模型有明显差异，导致现有的一些盲源分离的方法和算法难以适用于分布式天线接收的混合通信信号的分离。利用各源信号之间的统计独立性和通信信号的循环平稳性，提出了一种适合于分布式天线接收的混合通信信号盲分离的思想和实现方法。仿真实验表明，提出的方法能有效地分离出源信号。

| Abstract: | In non-cooperative communication environments,there are obvious differences between the signal model of "virtual antenna array" constituted by distributed antennas and the signal model of traditional blind source separation,which causes the existing algorithms of blind source separation to be inapplicable for separating the mixed signals received by distributed antennas.Based on the statistic independence of sources and the cyclo-stationarity of communication signals,an idea and approach to separate the mix... |
