<p>Problem: To provide an array antenna radio communication apparatus and a calibration method in which calibration can be carried out with high accuracy while suppressing interference with communication. Means for soluing the problem: Before starting communication, a recording section (114) records a highly reliable correction amount of phase rotation determined from a sufficient number of samples. During communication, a measuring section (112) measures the amount of phase rotation of a received known signal, a comparing section (113) compares the measured amount of phase rotation with the correction amount of phase rotation, and then the correction amount of phase rotation is updated, as required, according to the comparison results.</p> |
