Abstract
Récepteur AMRC à suppression parallèle d'interférences et à pondération. Les coefficients de pondération des sorties des différents étages du récepteur sont choisis pour minimiser une erreur quadratique pondérée par la distribution des valeurs propres de la matrice d'intercorrélation. Application en télécommunications.
