PURPOSE:To correctly synchronize a transmission phase between base stations even if the number of the base stations is large by sending a control signal to be the standard of a phase from a standard station by a system other than for a signal to a mobile station, and supervising and adjusting the phase of its own station by an adjusting station based on this control signal. CONSTITUTION:The standard station 1 is provided with a time slot extracting part 13 and a phase information transmitter 15 as a means to transmit the control signal to be the standard of the phase from the transmitter other than the transmitter 14 to send the signal to the mobile station, and the synchronizing means of the adjusting station 2 is provided with a time difference measuring part 25 as the means to receive the control signal from the standard station 1 and the transmission signal of its own station and obtain their phase difference, and is provided with a phase synchronization control part 26 and a variable delay circuit 22 as the means to adjust the transmission phase of its own station based on this phase difference. The control signal is supplied to the standard station 1 and the adjusting station 2 from a line control station 3 through an out going line. |
