【摘要】：針對盲信號處理中一種極端的病態(tài)混疊情況,單通道盲源分離是一個近年受到廣泛關注的重要研究方向,并且具有廣泛的應用前景.首先闡述了單通道盲源分離的數(shù)學模型、可分離性分析和分離效果評價標準,然后在深入研究單通道盲源分離發(fā)展的基礎上分類討論和評估了一些現(xiàn)有的單通道盲源分離方法,在介紹各方法的基本原理、特征及應用的同時,指出當前單通道盲源分離技術所面臨的問題與挑戰(zhàn).最后結(jié)合當前的研究狀況對單通道盲源分離未來的發(fā)展及研究方向進行了分析.
[Abstract]:For an extreme pathological aliasing in blind signal processing, single channel blind source separation is an important research direction which has been widely concerned in recent years, and has a wide application prospect. Firstly, the mathematical model of single-channel blind source separation, the analysis of separability and the criteria for evaluating the separation effect are described. Then, some existing single-channel blind source separation methods are discussed and evaluated on the basis of in-depth research on the development of single-channel blind source separation. In this paper, the basic principle, characteristics and application of each method are introduced, and the problems and challenges of single channel blind source separation technology are pointed out. Finally, the future development and research direction of single channel blind source separation are analyzed.
