ABSTRACT:
A radio frame synchronization system performs synchronization control of radio frames to be transmitted from a plurality of radio base stations respectively connected to wire lines to a mobile station. Each of the radio base stations includes a receiver, a sync signal detecting section, and a phase correcting section. The receiver receives a time-division radio signal to be transmitted from a distant radio base station in operation to the mobile station when a home radio base station is activated. The sync signal detecting section detects a sync signal from a reception output from the receiver. The phase correcting section generates a radio frame reference signal, indicating a timing at which a radio frame is transmitted to the mobile station, on the basis of a phase difference between the radio frame synchronization reference signal supplied from the wire line and the sync signal from the sync signal detecting section.
