Abstract

L'invention concerne un procédé et un dispositif pour ajuster la puissance de transmission de signaux. Le procédé consiste à obtenir un signal IQ numérique, un coefficient de montée du signal IQ numérique et un niveau de puissance de transmission du signal IQ numérique; à exécuter la montée numérique pour le signal IQ numérique selon le coefficient de montée et un modèle puissance/temps prédéterminé afin de générer un signal IQ numérique montant; à transformer le signal IQ montant en un signal IQ analogique montant; à ajuster la puissance de transmission du signal IQ analogique montant en fonction du niveau de puissance de transmission. Le dispositif comprend: un module d'obtention d'informations; un module de génération de signal IQ numérique montant; un module de transformation de signal analogique montant et un module d'ajustement de la puissance de transmission. Selon la présente invention, la précision du contrôle de la courbe de montée est améliorée, le modèle de montée est plus facilement respecté et l'efficacité de la montée en puissance est améliorée.
