Abstract
This paper addresses the problem of multi-channel blind speech separation in the instantaneous mixture case. We propose a new blind speech separation system which combines independent component analysis approach and the undecimated wavelet packet decomposition. The idea behind employing undecimated wavelet as a preprocessing step is to improve the non-Gaussianity distribution of independent components which is a pre-requirement for ICA and to increase their independency. The two observed signals are transformed using undecimated wavelet and Shannon entropy criterion into an adequate representation and perform then a preliminary separation. Finally, the separation task is done in time domain. Obtained results show that the proposed method gives a considerable improvement when compared with FastICA and other techniques.
