Abstract
A postdistortion amplifier that produces a postdistortion amplifier output signal based on a signal input to the postdistortion amplifier reduces distortion in the postdistortion amplifier output signal by digitally predistorting an error signal. The postdistortion amplifier includes a digital predistortion unit that receives a digital error signal and produces a digital predistorted error signal based on the received digital error signal and by reference to a predistorted error signal model.
