Abstract

Une méthode et un système de contrôle de puissance adaptatif pour une commande automatique de gain à large bande comprend la détermination qu’un signal est présent lorsqu’un dérivé de puissance du signal augmente, l’adaptation d’un gain pour une commande automatique de gain lorsque le signal est présent et la désactivation de l’adaptation lorsque le signal n’est pas présent.
