This paper considers a wavelet-based approach to the blind separation of signals (BSS) including reflections such as sound. The BSS for the instantateous mixture case is achieved by maximizing the mutual information between input and output signals or by zeroing the cross-correlations of separated signals. For making these methods applicable to the(More)
