【摘要】 盲信号分离是当前国际信号处理领域的研究热点,作为一种病态混叠情况,单通道盲信号分离是其刚刚兴起的一个重要研究方向,有着广泛的应用前景。首先阐述了单通道盲信号分离的数学模型、可分离性分析和分离效果评价指标,然后在深入研究单通道盲信号分离最新发展的基础上,对现有理论和方法进行了总结,并介绍了一些领域中的应用情况,最后指出其发展面临的挑战和进一步的研究方向。更多还原

【Abstract】 BSS(Blind Signal Separation) is currently a hotspot in the domain of signal processing in international community.As a case of ill-conditioned signal mixing,Single Channel Blind Signal Separation(SCBSS) is an aspect of particular interest and importance,as well as a new area of research,with a great future lying ahead.The mathematical model used for SCBSS,its separability and separation effect evaluation index are described in this paper.On the basis of an in-depth investigation into latest development of SCBSS,existing theories and methods are then classified and summarized,their application in some fields systematically explained.Finally,challenges and prospects for further development in the area are presented.更多还原
