Abstract

Disposición de procesamiento de señal para procesar una señal de entrada (x), comprendiendo la disposición de procesamiento de señal: - un amplificador (130) configurado para amplificar una señal procesada (y') para obtener una señal amplificada (y"); - un conversor descendente (150) configurado para multiplicar una versión de la señal procesada (y') por una versión de la señal amplificada (y"), estando una de las versiones de la señal desplazada en fase, para obtener una primera señal convertida descendentemente (z1, z1'), y multiplicar la señal procesada (y') por la señal amplificada (y") para obtener una segunda señal convertida descendentemente (z2, z2'); y - un predistorsionador adaptativo (110, 160) configurado para predistorsionar la señal de entrada (x) de acuerdo con una característica de predistorsión para obtener la señal procesada (y'), estando el predistorsionador (110, 160) configurado además para adaptar la característica de predistorsión en base a la primera señal convertida descendentemente (z1, z1') y la segunda señal convertida descendentemente (z2, z2').
