Abstract

Le procédé utilise la technique de codage CELP à répertoire algébrique. La recherche de l'excitation CELP comporte un calcul de certaines composantes de la matrice de covariance U = HT.H où H désigne une matrice triangulaire inférieure de Toeplitz formée à partir de la réponse impulsionnelle d'un filtre composé de filtres de synthèse et d'un filtre de pondération perceptuelle. Les composantes mémorisées de la matrice de covariance sont seulement celles de la forme U(posi,p, posi,p) et celles de la forme U(posi,p, posj,q,) posi,p et posj,q désignant respectivement la position i et la position j pour les impulsions p et q dans les codes du répertoire algébrique.
