PURPOSE:To execute the phase adjustment being suitable for a new signal transmission path in a short time by reading out the phase correction quantity from a memory area corresponding to the new signal transmission path at the time point when switching of the signal transmission path from a master station is detected, and setting it to a phase adjusting part. CONSTITUTION:The system is provided with a storage part 3 for storing the phase correction quantity corresponding to each of signal transmission paths l0, l1 from a master station, and whenever the phase adjustment is executed, the phase correction quantity corresponding to the signal transmission path from the master station in the storage part 3 is updated. On the other hand, at the time point when it is detected that the signal transmission path from the master station is switched, the phase correction quantity corresponding to the signal transmission path connected newly is read out of the storage part 3 and set to a phase adjusting part 4. In such a way, a phase of a call signal can be adjusted quickly without waiting for the next phase adjustment request from the master station, and the service can be offered without generating the deterioration of a receiving rate of a moving machine caused by a shift of the phase of the call signal radiated from a base station.
