Clock synchronization method, receiver, transmitter, and clock synchronization system

Abstract

A clock synchronization method, a receiver, a transmitter, and a clock synchronization system, where the method includes obtaining a common reference clock signal, determining Baccording to the common reference clock signal and Mr(t−1), where determining that Mr(t−1) is a target Mrwhen Cobtained by means of calculation according to Mr(t−1) is less than or equal to a threshold, where C=B−A, Ais included in a residual time stamp (RTS) packet received by a receiver last time from the transmitter, and performing frequency division on the common reference clock signal using the target Mras a frequency dividing coefficient to obtain a first clock signal, and performing frequency multiplication processing on the first clock signal to obtain a service clock signal. Hence, random phase offset may be avoided.
