摘 要：In this paper,we consider the problem of blind identification in the underdetermined instantaneous mixtures case,where there are more sources than ***,a simultaneous matrix diagonalization(SMD)-based method has been proposed without any need of sparsity assumption on *** of using SMD technique,we propose a fixed point algorithm,which estimates the columns of the mixing matrix sequentially one by *** simulations are presented in order to demonstrate that the proposed algorithm has the ability to identify the mixing matrix,and its performance is comparable to that of SMD-based algorithm.
