Source separation in strong noisy mixtures: A study of wavelet de-noising pre-processing

This paper addresses the source separation in strong noisy mixtures by wavelet de-noising processing. Experiments include the cases of white/correlated Gaussian and non- Gaussian noise, which correspond to various applications. The performance of BSS/ICA algorithms after wavelet de- noising is quantitatively investigated, and points out the efficiency of the method.
