Abstract

In a case where transmission and reception timing of a base station has not been synchronized to that of another base station in the vicinity, or in a case where it is necessary to establish such synchronization, a synchronous controller outputs a reception-mode changeover signal to change the prevailing mode from an ordinary reception mode to a synchronous control reception mode. As a result, attenuating means attenuates a strong input signal from the other base station and enters the attenuated signal into a demodulator via a front end. The demodulator proceeds to demodulate the received data. The synchronous controller detects synchronization information (a synchronizing word) from the received data to synchronize the transmission and reception timings of the two base stations and then returns the reception mode to the ordinary reception mode.
