Dominique Pastor, Gérard Reynaud, Pierre Albert Breton: Method of frequency filtering applied to noise suppression in signals implementing a wiener filter. Sextant Avionique, Oblon Spivak McClelland Maier & Neustadt P C, September 3, 2002: US06445801 (20 worldwide citation)

The disclosed method uses the Wiener frequency filtering to suppress noise in noisy sound signals (u(t)). This method includes a preliminary step in which the sound signals (u(t)) to be noise-suppressed are digitized by sampling and subdivided into frames. The method then includes a first series of ...
