Prewhitening is often considered a necessary but not sufficient condition for stronger stochastic independence criteria. After prewhitening the task of Blind Source Separation (BSS) become somewhat easier. Robust preprocessing involves spectral whitening, which is done by transforming correlated signals to an uncorrelated flat spectrum signal. The maximum entropy power spectrum estimation has b...

A novel subspace approach for speech enhancement using a subband whitening filter is proposed. Previous subspace approaches for enhancement either assumed white noise or used a fullband pre-whitening filter before enhancement for colored noise. The previous approaches were successful only in reducing the upper bound of the signal distortion while reducing noise. However, the proposed method min...
