Array-antenna radio communication apparatus |
摘要 |
A reception radio circuit 104 and a reception radio circuit 105 receive radio communication signals from a mobile station 109 and calibration signals from a CAL-CDMA radio signal transmission section 110 through respective a reception antenna 102 and a reception antenna 103, followed by performing down-conversion of received signals. A reception CDMA signal processing section B (for CAL) 107 measures characteristic errors of respective reception radio circuits while observing the calibration signals undergoing down-conversion, before holding the measured characteristic errors in a compensation table of a recorder 108. A reception CDMA signal processing section A (for communication) 106 performs CDMA demodulation processing of radio communication signals from the mobile station 109, which signals are subjected to the down-conversion, at the same time as observing operation of the reception CDMA signal processing section B (for CAL) 107, on the basis of the characteristic errors held in the compensation table.
