Novel Independent Component analysis(ICA) algorithm for hybrid sources separation based on constrained optimization—exterior penalty function method is proposed. The proposed exterior penalty ICA algorithm is under the framework of constrained ICA(cICA) method to solve the constrained optimization problem by using the exterior penalty function method. In order to choose nonlinear functions as the probability density function(PDF) estimation of the source signals, generalized k-nearest neighbor(GKNN) PDF estimation is proposed which can separate the hybrid mixtures of source signals using only a flexible model and more important it is completely blind to the sources. The proposed EX-cICA algorithm provides the way to wider applications of ICA methods to real world signal processing. Simulations confirm the effectiveness of the proposed algorithm.
