Abstract:
A receiver includes a frequency converter configured to generate a I signal and a Q signal from each band of a multiband signal and a mismatch compensator configured to estimate a mismatch of the I signal and the Q signal for each of the bands of the multiband signal and store at least one compensation value to compensate for the estimated mismatch. The frequency converter compensates for the mismatch of the I signal and the Q signal based on the at least one compensation value.
