摘要：A reception radio circuit 104 and a reception radio circuit 105 receive radiocommunication signals from a mobile station 109 and calibration signals from a CAL-CDMA radio signal transmission section 110 through respective a reception antenna 102and a reception antenna 103, followed by performing down-conversion of receivedsignals. A reception CDMA signal processing section B (for CAL) 107 measures

characteristic errors of respective reception radio circuits while observing the calibrationsignals undergoing down-conversion, before holding the measured characteristic errorsin 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 thedown-conversion, at the same time as observing operation of the reception CDMA signalprocessing section B (for CAL) 107, on the basis of the characteristic errors held in thecompensation table.
