Abstract

On détermine un débit de communication dans un système de communications à débit variable en calculant des métriques en fonction de l'énergie par symbole sur une trame de canal de trafic (200) ainsi qu'en sélectionnant un débit optimal d'après ces métriques calculés. On calcule ces derniers grâce à une accumulation sélective de l'énergie par symbole, en faisant appel à des circuits d'addition (405, 408) et à des éléments d'accumulateur (409, 412) en réaction à la présence de groupes de commande de puissance (201) dans la trame du canal de trafic (200) comme déterminé par le sélecteur (400) de groupe de commande de puissance.
