Abstract

The array antenna radio communication apparatus of the present invention combines the outputs of calibration desired signal generator 101 and calibration interference signal generator 102 using combination section 104. When changing the power of the combined calibration signal, it fixes the power of calibration desired signal to avoid phase rotations due to the power control section and changes only the power of the calibration interference signal by power control section.
The array antenna radio communication apparatus supplies this combined calibration signal to a plurality of radio circuits simultaneously or alternately and performs reception processing on only the calibration desired signal by received signal processing section 112 and measures reception characteristics.
