Abstract—This paper proposes a new fast method for identifying the mixing matrix based on a binary state mixture of Gaussian (MoG) source model. First, a necessary discussion for solving the mixing matrix detection is offered under the multiple dominant circumstance. Second, a density detection method is presented to improve the identification performance. Simulations are given to demonstrate the effectiveness of our proposed approach.

Index Terms—blind source separation (BSS); sparse component analysisSCA; density detection; mixture of Gaussian (MoG) model.
