Abstract :
In this paper, a second order separation algorithm of nonstationary using temporal structure and linear prediction model was proposed. The blind source separation algorithms based on second order statistics can work well when the sources have temporal structure. Our method had a low computation and a loose request for sources independency. It is not sensitive to additive white noise. Simulations showed the better performance of the proposed algorithm.
