This paper proposes a nonlinear principle component analysis (PCA)cost function for blind separation of convolutive mixtures.Then a new recursive least-squares (RLS) algorithm is developed in time domain.This algorithm has two stages:one is whitening
the other is RLS iteration.Also
the algorithm does not suffer from the problems of frequency domain based algorithms on arbitrary scaling and permutations in different frequency components.Simulations show that this algorithm can successfully separate mixing signals and has fast convergence.
