Abstract: Dealing with the underdetermined linear instantaneous mixing blind source separation problem, the mixing matrix estimation and source signals recovery based on a "two-step" method are concerned, the刘 research status at home and abroad are summarized, the theoretical problems that limit the application of undetermined blind source separation (UBSS) algorithms are analyzed, which make preparations for a further study of UBSS.

Key words: underdetermined blind source separation, mixing matrix estimation, source signal recovery, sparsity, observed source signal dimension expansion
