Abstract
L'invention porte sur une ligne de communication comportant: plusieurs paires de fils torsadés, plusieurs émetteurs (A, B, C, D, E, F, G, H) à raison d'un par extrémité de paire, et plusieurs récepteurs (A, B, C, D, E, F, G, H), à raison d'un par extrémité de paire, l'ensemble constituant un système de télécommunications à niveau d'erreur préétabli. Chaque récepteur reçoit un signal combiné comprenant un signal direct provenant de l'émetteur placé à l'extrémité opposée de la paire à laquelle le récepteur est associé, et plusieurs signaux de bruit. Plusieurs filtres adaptatifs répondent au signal combiné, et chacun d'eux est muni de plusieurs prises associées chacune à un coefficient et pouvant commuter entre un état actif et un état inactif. Un élément de commande permet d'ajuster les fonctions de transfert d'au moins l'un des filtres adaptatifs en désactivant sélectivement les prises tout en garantissant que l'erreur du système du communication ne dépasse pas l'erreur seuil.
