INTER-BASE STATION SYNCHRONIZATION SYSTEM, SYNCHRONIZATION CONTROL DEVICE, AND BASE STATION

摘要

[PROBLEMS] To provide an inter-base station synchronization system, a synchronization control device, and a base station capable of accurately synchronizing a plurality of base stations. [MEANS FOR SOLVING PROBLEMS] An inter-base station synchronization system includes a plurality of base stations (13) and a base station line collection device (12). The base station line collection device (12) has a control information generation unit (21) for generating synchronization control information. Each of the base stations (13) has a VCO (30) for oscillation with a frequency based on a control voltage inputted and a correction unit (33) for correcting the control voltage inputted into the VCO (30). Thus, it is possible to mutually synchronize the original oscillation clock in the plurality of base stations, suppress a phase difference between the base stations, and accurately synchronize the base stations.
