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。
In conventional radio spectrum monitoring, there is no effective monitoring method for the mixed signals with overlapping frequency bands in the same frequency band. Blind source separation can separate the received mixed signal without the need of known source signals and propagation channels to obtain pure Source signal, is to achieve effective monitoring of such mixed signals, so consider the blind source separation applied to the spectrum management monitoring. The basic concepts of blind source separation are introduced, and the blind source separation algorithm of short wavelength spectrum management monitoring is analyzed. The application of this technique in electromagnetic spectrum management and monitoring is emphatically simulated, which provides technical support for spectrum management and monitoring.
