PURPOSE:To ensure the synchronization of a signal of each radio base station with high accuracy even if a delay time of a signal in any part of the system on its way varies by comparing a phase of the signal through a radio system. CONSTITUTION:An m-order base station sends a radio wave in a time slot where an m-order peripheral station stops its own radio wave. Thus, the radio wave is received by a receiver in its own station and the phase of the signal of the m-order base station is stored in a comparator circuit. A radio wave is sent from both the stations in a common time slot and since the radio wave of its own station is far stronger than the radio wave from the base station, only the radio wave of the peripheral station is received and the phase of the signal of its own station is detected, and it is compared with the phase of the signal of the base station stored therein to detect a difference. |
