<p>A wireless communication device (1) which permits reduction in the scale of circuitry as well as in the power consumption. The wireless communication device (1) includes an array of antennas (1-1 to 1-n), an adaptive array searcher (1a), and a data demodulator (1c). The adaptive array searcher (1a) detects the phase difference between the antennas and estimates the direction of arrival of received radio waves. The data demodulator (1c) demodulates the radio signal received by the antennas. The adaptive array searcher (1a) shares part of circuitry with a calibrator (1b) which performs calibration by correcting the phase difference caused between antenna channels in the wireless communication device, and thus has a calibration function incorporated therein.</p> |
