Abstract

L'invention concerne un dispositif de commande de gain qui fonctionne pour réguler le gain dans chacune des voies de signaux de liaison descendante et de liaison montante à large bande. On détecte des signaux souhaités faibles, à l'intérieur de chaque voie de signaux à large bande en utilisant un convertisseur abaisseur de bande étroite et un détecteur, ces signaux souhaités étant contrôlés par un micro-contrôleur. En fonction des signaux contrôlés, le micro-contrôleur fonctionne, sous la commande d'un logiciel approprié installant un algorithme de contrôle adaptatif, de manière à ajuster le gain dans chacune des voies montante et descendante en vue d'optimiser de façon dynamique la capacité .
