(FR) FILTRE ADAPTATIF A STRUCTURE EN TREILLIS DES MOINDRES CARRES RECURSIFS A COMPLEXITE REDUITE OBTENU PAR APPROXIMATION DES CARRES DE PREDICTION DES ERREURS AVAL AU MOYEN DES CARRES DE PREDICTION DES ERREURS AMONT
Abstract: front page image
(EN)A method for reducing a computational complexity of an m-stage adaptive filter is provided by determining a weighted sum of backward prediction error squares for stage m at time n, determining a conversion factor for stage m at time n, inverting the weighted sum of backward prediction error squares, and approximating a weighted sum of forward prediction error squares by combining the inverted weighted sum of backward prediction error squares with the conversion factor.
(FR)L'invention concerne un procédé permettant de réduire la complexité de calcul d'un filtre adaptatif à étape m et consistant à déterminer une somme pondérée des carrés d'erreur de prédiction amont pour l'étage m à un moment n, à déterminer un facteur de conversion pour l'étage m à un moment n, à inverser la somme pondérée des carrés d'erreur de prédiction amont et à faire une approximation d'une somme pondérée des carrés d'erreur de prédiction aval par combinaison de la somme pondérée inversée des carrés d'erreur de prédiction amont avec le facteur de conversion.
