Array antenna radio communication apparatus and calibration method |
摘要 |
The recording section 114 records a highly reliable amount of correction for phase rotation, which is obtained in advance by a sufficient number of samples before commencement of communications. The measurement section 112 measures the amount of phase rotation of the known signals, and the comparison section 113 compares the measured amount of phase rotation with the amount of correction and renews the amount of correction from time to time during communications on the basis of the results of the comparison.
