The present invention is a method and system for extracting information from a received signal (Yi) with minimal loss due to noise. The system comprises of a transformer (12), for correlating the received signal to a wavelet function and producing wavelet decomposition coefficients, and a threshold circuit (20), which is responsive to the received signal (Yi), for applying predetermined threshold values based on the type of signal. Also included in the system is a filter (13), coupled to the transformer (12) and threshold circuit (20), for altering the wavelet decomposition coefficients produced by the transformer (12) using threshold values applied by the threshold circuit (20) to produce altered wavelet coefficients from which the received signal (Yi) is reconstructed with reduced noise.

La présente invention concerne un procédé et un système permettant d'extraire des informations d'un signal reçu avec un minimum de perte due au bruit. Ledit système comprend un transformateur servant à mettre en corrélation le signal reçu et une fonction par ondelettes et à produire des coefficients de décomposition en ondelettes, ainsi qu'un circuit à seuil qui réagit au signal reçu pour appliquer des valeurs seuils prédéterminées d'après le type de signal. Ce système comprend également un filtre qui est couplé au transformateur et au circuit à seuil pour modifier les coefficients de décomposition en ondelettes produits par le transformateur au moyen de valeurs seuils appliquées par le circuit à seuil de façon à produire des coefficients en ondelettes modifiés, à partir desquels le signal reçu est reconstruit avec un bruit réduit.
