Abstract

A method for calibrating compensation values utilized by a compensation device in a transmitter includes: obtaining a plurality of output signals sequentially generated by the transmitter by processing a pair of input signals based on a plurality of pairs of compensation values as a plurality of feedback signals, where each feedback signal corresponds to one of the plurality of pairs of compensation values; obtaining a signal component of the feedback signals at a predetermined frequency as a portion of the feedback signals; determining a pair of equivalent impairment parameters in a calibration operation according to the plurality of pairs of compensation values and the portion of the feedback signals; and determining a pair of calibrated compensation values according to the pair of equivalent impairment parameters and providing the pair of calibrated compensation values to the compensation device.
