A method and system for adjusting the amplitude and phase characteristics of wireless communication signals generated by an analog radio transmitter, based on transmit power control (TPC) signals received by a base station (BS) and known characteristics of a power amplifier (PA) included in the transmitter. A digital pre-distortion compensation module, having real and imaginary signal paths, receives and processes real and imaginary signal components used to generate the wireless communication signal. The phase and amplitude characteristics of the wireless communication signal are controlled in response to the TPC signals, such that impaired amplitude and phase characteristics of the PA are corrected.
La présente invention concerne un procédé est un système de réglage des caractéristiques d'amplitude et de phase de signaux de communication sans fil générés par un émetteur radio analogique, à partir de signaux de commandes de puissance d'émission (TPC) reçus par une station de base (BS) et de caractéristiques d'un amplificateur de puissance (PA) inclus dans l'émetteur. Un module de compensation de pré-distorsion numérique, possédant des trajets de signal réel et imaginaire, reçoit et traite des composants de signal réel et imaginaire utilisés pour générer le signal de communication sans fil. Des caractéristiques de phrase et d'amplitude du signal de communication sans fil sont commandés en réponse aux signaux TPC, de façon que des caractéristiques d'amplitude et de phase erronées de l'amplificateur PA soient corrigées.
