Title (EN) COMPENSATION PARAMETER AND PREDISTORTION SIGNAL
(FR) PARAMÈTRE DE COMPENSATION ET SIGNAL DE PRÉDISTORSION
Abstract:
(EN) A controller (52) can include a signal generator (54) configured to provide an input signal to a modulator (46). The controller (52) can be configured to generate a modulator compensation parameter in response to a modulated feedback signal corresponding to an output of the modulator (56). The controller (52) can also be configured to generate a power amplifier predistortion signal in response to an amplified feedback signal corresponding to an output of a power amplifier (62) coupled to the modulator (56).
(FR) Un contrôleur (52) peut comprendre un générateur de signaux (54) conçu pour fournir un signal d'entrée à un modulateur (46). Le contrôleur (52) peut être conçu pour générer un paramètre de compensation de modulateur en réponse à un signal de réaction modulé correspondant à une sortie du modulateur (56). Le contrôleur (52) peut également être conçu pour générer un signal de prédistorsion d'amplificateur de puissance en réponse à un signal de réaction amplifié correspondant à une sortie d'un amplificateur de puissance (62) couplé au modulateur (56).
