Abstract: A method employed by a circuit included within a receiver apparatus and configured for performing IQ mismatch compensation when receiver apparatus is operating under data reception mode includes: transforming a data signal, which is generated by a radio frequency receiver under the data reception mode, from time domain into a plurality of frequency bin signals in frequency domain; calculating to obtain at least one frequency domain calibration parameter according to the plurality of frequency bin signals in frequency domain; and, updating at least one coefficient parameter of IQ mismatch compensation according to the obtained at least one frequency domain calibration parameter, to make IQ mismatch compensation compensate IQ mismatch based on the updated at least one coefficient parameter.
