Abstract
A embodiment method, for linearizing a transmission signal resulting from a quadrature amplitude modulation of an analog baseband signal and a radiofrequency amplification, comprises a demodulation of a feedback signal taken from the transmission signal, a comparison between the demodulated feedback signal and the baseband signal, a digital calculation of a predistortion control signal based on the comparison, and an analog predistortion of the analog baseband signal controlled by the predistortion control signal.
