摘要
针对盲信号处理中一种极端的病态混叠情况,单通道盲源分离是一个近年受到广泛关注的重要研究方向,并且具有广泛的应用前景.首先阐述了单通道盲源分离的数学模型、可分离性分析和分离效果评价标准,然后在深入研究单通道盲源分离发展的基础上分类讨论和评估了一些现有的单通道盲源分离方法,在介绍各方法的基本原理、特征及应用的同时,指出当前单通道盲源分离技术所面临的问题与挑战.最后结合当前的研究状况对单通道盲源分离未来的发展及研究方向进行了分析.
As a case of ill-conditioned signal mixing,the single channel blind source separation（SCBSS） is an important research field which has been widely given attention and has broad application prospects. The mathematical model of SCBSS and the evaluation index of separation effect are described firstly. Secondly,on the basis of an in-depth investigation into latest development of SCBSS,some kinds of existing theories and methods are then emphatically discussed and summarized,then the applications of the methods presented are systematically explained. Finally the challenges and prospects for further development in the area are listed.
