Abstract

La présente invention se rapporte au domaine des communications. L'invention concerne un dispositif de traitement de signal capable de résoudre le problème de forte consommation d'énergie lorsqu'une couche de commande d'accès au support (MAC) traite des données dans un système de communication à modulation d'amplitude à plusieurs étages. La solution spécifique est : acquisition de signaux initiaux ; division des signaux initiaux en N -1 trajets de signal ; acquisition d'un signal de commande de sélection ; et, conformément au signal de commande de sélection, sélection d'un ou plusieurs parmi M trajets de signal pour un décodage logique, de sorte que la couche MAC a seulement besoin de traiter les signaux de décodage de certains des signaux initiaux, ce qui permet d'économiser des ressources de largeur de bande et de réduire la consommation d'énergie pendant le traitement des données de la couche MAC.
