Abstract
A wireless communication apparatus includes a plurality of antenna branches through which radio signals are transmitted and received; a calibration factor acquiring unit that acquires a calibration factor for compensating an unbalance of phase and amplitude between the antenna branches for every predetermined frequency band; a factor memory storing the calibration factor acquired for every predetermined frequency band; a reliability determining unit that determines a reliability of the calibration factor acquired by the calibration factor acquiring unit; and a calibration factor multiplying unit that reads out the calibration factor from the factor memory to multiply a transmission signal or a reception signal to be calibrated by the readout calibration factor.
