Abstract: 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.

Key words: blind source separation, single channel, signal processing
