Abstract
A digital pre-distortion circuit and a method for reducing clipping noise in a digital pre-distortion circuit are provided. The digital pre-distortion circuit includes a pre-distorter, a clipping logic, an error extraction circuit, a filter and a compensation circuit. The pre-distorter performs a pre-distortion operation according to an input signal to generate an initial pre-distortion signal, and the clipping logic clips the initial pre-distortion signal to generate a clipped pre-distortion signal. In addition, the error extraction circuit calculates a difference between the initial pre-distortion signal and the clipped pre-distortion signal to generate a clipped error signal, and the filter performs filtering on the clipped error signal to generate a filtered error signal, wherein the compensation circuit compensates the clipped pre-distortion signal according to the filtered error signal to generate an output signal.
