Abstract
L'invention concerne un procédé et un système pour fournir une commande de puissance adaptative pour une commande de gain automatique à large bande (WB-AGC) comprenant : la détermination d'un signal qui est présent lorsqu'une dérivée de puissance du signal augmente ; l'adaptation d'un gain pour une commande de gain automatisée (AGC) lorsque le signal est présent ; et la désactivation de l'adaptation lorsque le signal n'est pas présent.
