Considering the deficiency of nonlinear parameter estimation in post-nonlinear mixtures BSS, we propose a method based on an improved GA. First, the value of a new fitness function is used to reflect on the choice of crossover and mutation probabilities. PE and SA are incorporated in GA. Finally, the linear separation algorithm is applied to estimate the separation matrix. The results indicate that the new method has better performance than conventional algorithms.
