PURPOSE:To enable the synchronization between plural radio base stations without performing a test and an adjustment. CONSTITUTION:In a master radio base station 10a, a line interface part 11a extracts a frame synchronizing signal (1). A timing generation part 16a generates a TDMA frame synchronizing signal (2) from the frame synchronizing signal (1). A delay part 17 outputs a signal (3) where the TDMA frame synchronizing signal is delayed for one frame of the frame synchronizing signal. In a slave radio base station 10b, a line interface part 15b extracts a frame synchronizing signal (4). The frame synchronizing signal (4) is the same signal as the frame synchronizing signal (1). A radio frame transmission timing signal generation part 18 synchronizes the frame synchronizing signal (4) with a TDMA frame synchronizing signal (5) and outputs a radio frame transmission timing signal (6). Because the TDMA frame synchronizing signal (5) has a transmission delay, the phase of a radio frame transmission timing signal (6) matches with that of the signal (3). |
