FREQUENCY SYNCHRONIZATION DEVICE, RADIO BASE STATION, FREQUENCY SYNCHRONIZATION PROGRAM AND FREQUENCY SYNCHRONIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a novel frequency synchronization device that can establish frequency synchronization using an IP network.;SOLUTION: A frequency synchronization device 10 for synchronizing a clock frequency between a master device 102 and a slave device 103 has a frequency offset calculator 12 for calculating a frequency offset O which is a deviation of the clock frequency of the slave device 103 from the clock frequency of the master device 102, and a synchronization calculator 14 for calculating an interval time T till execution of synchronization processing of synchronizing the clock frequency next time on the basis of a residual frequency offset O_res remaining after the frequency offset O is multiplied by a convergence coefficient, and a minimum frequency unit adjustable in the slave device 103.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
