Abstract
(EN)
A method and an apparatus. The apparatus includes at least one sensor for sensing at least one parameter that affects a non-linearity of the non-linear amplifier and for generating at least one parameter indicator; a memory module for storing multiple sets of pre-distortion coefficient values; a retrieval module, coupled to the memory module, for receiving the at least one indicator, for selecting a selected set of pre-distortion coefficient values based on the at least one indicator, and for sending the selected set of pre-distortion coefficient values to a signal processing module; and a signal processing module, configured to receive an input signal, to receive the selected set of pre-distortion coefficient values, and to pre-distort the input signal, using the selected set of pre- distortion coefficient values such as to at least partly compensate for the non-linearity of the non-linear amplifier.

L'invention porte sur un procédé et un appareil. L'appareil comprend au moins un détecteur pour détecter au moins un paramètre qui affecte une non-linéarité de l'amplificateur non linéaire et pour générer au moins un indicateur de paramètre ; un module de mémoire pour stocker de multiples ensembles de valeurs de coefficients de prédistorsion ; un module de récupération, couplé au module de mémoire, pour recevoir l'au moins un indicateur, pour sélectionner un ensemble sélectionné de valeurs de coefficients de prédistorsion sur la base de l'au moins un indicateur, et pour envoyer l'ensemble sélectionné de valeurs de coefficients de prédistorsion à un module de traitement de signal ; et un module de traitement de signal, configuré pour recevoir un signal d'entrée, pour recevoir l'ensemble sélectionné de valeurs de coefficients de prédistorsion et pour prédistordre le signal d'entrée, à l'aide de l'ensemble sélectionné de valeurs de coefficients de prédistorsion, de façon à compenser au moins partiellement la non-linéarité de l'amplificateur non linéaire.
