Abstract
We propose a new method of blind source separation for convolutive mixtures. We use a wavelet transform which can get information from the two sides of time and frequency when we change the observed signals into the time-frequency domain. Our idea is to use a new estimation equation of the separating matrix for time delay. We aim to improve the separation performance. We show the result of desktop simulation of artificially controlled data.
