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 B t  according to the common reference clock signal and Mr d (t−1), where B t = mod  [ ∑ n = 0 t - 1   Mr d  ( n ) , 2 p ] , determining that Mr d (t−1) is a target Mr d  when C t  obtained by means of calculation according to Mr d (t−1) is less than or equal to a threshold, where C t =B t −A t , A t  is included in a residual time stamp (RTS) packet received by a receiver last time from the transmitter, and A t = mod  [ ∑ n = 0 t   M d  ( n ) , 2 p ] , performing frequency division on the common reference clock signal using the target Mr d  as 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.

Claim (Index 9):
A clock synchronization method, comprising:\n obtaining, by a transmitter, a service clock signal, a frequency of the service clock signal comprising f s ; dividing, by the transmitter, the f s  by a factor N; determining, by the transmitter, a residual time stamp (RTS) period (T) of sending an RTS packet by the transmitter, the T = N f s , and the N being greater than one;\n determining, by the transmitter, a quantity of clock periods of a common reference clock signal within an n th  T (M q (n)), a frequency of the common reference clock signal comprising f n ; \n calculating, by the transmitter, information about a frequency offset (M d (n)) between the f s  and the f n  using a formula M d (n)=M q (n)\u2212M nom  and the M q (n), the M nom , comprising a reference quantity of clock periods of the common reference clock signal within the n th  T obtained by the transmitter, and the n comprising a positive integer; \n calculating, by the transmitter, A t  using a formula \n A t = mod \ue89e [ \u2211 n = 0 t \ue89e \ue89e M d \ue8a0 ( n ) , 2 p ] and according to the M d (n), the P comprising a bit width of a counter in the transmitter configured to record a quantity of rising edges of the common reference clock signal in the transmitter within the n th  T; and\n sending, by the transmitter, the RTS packet comprising the A t  to a receiver.
