Abstract

RECEPTEUR DE DONNEES COMPRENANT SUCCESSIVEMENT, EN AMONT D'UN CIRCUIT DE DECISION, UN RESEAU NUMERIQUE ADAPTATIF A PLUSIEURS COEFFICIENTS QUI COMPENSE LE TERME PREPONDERANT DE LA FONCTION DE TRANSFERT DE LA LIGNE DE TRANSMISSION ET UN SECOND RESEAU A PETIT NOMBRE DE COEFFICIENTS. LE CIRCUIT DE COMMANDE DU SECOND ETAGE COMPARE UN COEFFICIENT DE CELUI-CI A DES BORNES ET, A CHAQUE DEBORDEMENT, REPORTE LES COEFFICIENTS DU SECOND ETAGE DANS LE PREMIER. CE CIRCUIT DE COMMANDE DEDUIT DE PLUS, DE L'EVOLUTION DU COEFFICIENT DU SECOND ETAGE, UNE ESTIMATION DE LA DERIVE DE FREQUENCE QUI EST FOURNIE A DES MOYENS DE CORRECTION 22. APPLICATION A LA TRANSMISSION DE DONNEES SUR LIGNES TELEPHONIQUES.
