Abstract
Un procédé pour linéariser un signal de transmission (RF_TX) résultant d’une modulation d’amplitude en quadrature (QAM mod) d’un signal en bande de base analogique (BB_TX) et une amplification en radiofréquence (RFPA), comprend une démodulation (QAM demod) d’un signal de rétroaction provenant du signal de transmission (RF_TX), une comparaison (COMP) entre le signal de rétroaction démodulé (BB_FB) et le signal en bande de base (BB_TX), un calcul numérique (DPD_CU) d’un signal de commande de prédistorsion (PD_CT) basé sur la comparaison, et une prédistorsion analogique (APD) du signal en bande de base analogique (BB_TX) commandée par le signal de commande de prédistorsion (PD_CT).
