摘　　要：盲源分离是指在不知道源信号和传输信道任何先验知识的情况下,仅根据输入源信号的统计特性,通过观察信号恢复出各个独立源信号的过程。文章简要介绍了盲源分离的基本思想、概念及数学模型,并对目前在盲源分离研究中,几个关键问题取得的研究成果与进展进行了讨论。Blind source separation is to recover sources from their mixtures based on statistical characteristic of the sources without the prior knowledge of the sources and the mixing channels. The basic idea, concept and mathematic model of blind source separation are briefly introduced in the paper. Some achievements and development on the key problems of blind source separation are also discussed.
