Noise suppression in cellular communications
Hynek Heřmanský, Eric A. Wan, C. Avendaño · 2002
FIR Wiener-like filters are applied to time trajectories of cubic-root compressed short-term power spectrum of noisy speech recorded over cellular communications. Informal listenings indicate that the technique brings a noticeable improvement in quality of noisy speech in the overlap-add analysis-synthesis system while not causing any significant degradation on clean speech.>
