Abstract
A communications device and a method for compensating frequency response distortion of the communication device are provided. The communications device includes a transmitting path circuitry, a receiving path circuitry, a memory pre-distortion circuit, a pre-equalizer circuit and a pre-equalization calculation circuit. The transmitting path circuitry and the receiving path circuitry are configured to generate a feedback signal according to a pre-distortion test signal, where a set of pre-distortion coefficients of the memory pre-distortion circuit are calibrated according to the feedback signal. After calibration of the set of pre-distortion coefficients is finished, the pre-equalization calculating circuit performs calculation on the set of pre-distortion coefficients to generate a calculation result for calibrating the pre-equalizer circuit. After calibration of the pre-equalizer circuit is finished, a transmission signal is processed by the pre-equalizer circuit and the memory pre-distortion circuit first, and then output to outside of the communications device via the transmitting path circuitry.
