Abstract :
A blind source separation method based on generalized eigendecomposition of time delayed correlation matrices in the wavelet domain is proposed. The wavelet domain algorithm can separate the mixtures when the number of the sources is more than three, while the time domain algorithm can´t. The proposed method is a fast, stable and easy to implement algorithm. The computer simulations results demonstrate the correctness and effectiveness of the proposed algorithm
