To accurately determine a base station, after inter-cell diversity handovers (DHO).

A received-data conversion circuit 115 performs error detection, based on CRC coding over a demodulated received data and outputs a result (OK or NG) of the CRC detection. A TFCI demodulation circuit 116 extracts transport format information (TFCI signal) from the demodulated received data, calculates the correlation value for the extracted TFCI signal and outputs it. When the CRC detection result is not good in both cases, a control station 103 compares the correlation values of the TFCI signals received from two base stations 101 and 102, and selects larger one of the correction values of the two base stations 101 and 102, and continues communication with the selected base station.
