摘要
常规无线电频谱监测中,对同频段频谱相互重叠的混合信号缺乏有效的监测手段,盲源分离能在不需要已知源信号和传播信道的情况下,实现对接收混合信号的分离,得到纯净的源信号,是实现监测这种混合信号的有效方法,所以考虑将盲源分离应用到频谱管理监测中。介绍了盲源分离的基本概念,对短波频谱管理监测的盲源分离算法进行了分析,着重对该技术在电磁频谱管理监测中的应用进行了仿真,为频谱管理监测提供了技术支持。
Traditional radio spectrum monitoring lacks effective monitoring on the mixed signals overlapped in the same frequency bands spectrum.In the circumstance that the source signal and the propagating channel are unknown,the blind source separation could separate mixed signals and obtain pure source signal,so is an effective method for monitoring this mixed signals.Thus the blind source separation is applied to spectrum management monitoring.This paper describes the concept of blind source separation,and analyzes the algorithm of blind source separation for short wave spectrum management monitoring.The application of this technology in the electromagnetic spectrum management monitoring is simulated,thus providing certain technical support for spectrum management monitoring.
