SYNCHRONIZATION METHOD AND DEVICE

摘要

A synchronization method is provided in the present invention, which includes: acquiring the synchronization symbol location d 0 of a time slot in the initial update period; adjusting the synchronization symbol location as N track frames are regarded as an update period, wherein the step of adjusting includes: according to the synchronization symbol location d k of the corresponding time slot in the k-th update period and the interframe sampling deviation estimated value T k of said k-th update period, acquiring the synchronization symbol location d k+1 =d k +N track T k of the corresponding time slot in the (k+1)-th update period, wherein the corresponding time slot is the time slot corresponding to the location of said time slot in said initial update period; according to the synchronization symbol location d k of the corresponding time slot in the k-th update period and the interframe sampling deviation estimated value T k of said k-th update period, acquiring the synchronization symbol locations of the other time slots in said k-th update period, wherein the interframe sampling deviation estimated value T k is the estimated value for the deviation of the synchronization symbol location in one frame, k=0; thus realizing the timing synchronization. Also a synchronization device is provided in the present invention. The method and device of the present invention enable the synchronization symbol location to be updated by using the periodicity of the broadcast system, enable the other synchronization symbol locations in the same update period to be acquired by sampling the synchronization predication, and enable the amount of synchronization calculation to be reduced.
