Claim:
A synchronization method, comprising: obtaining a synchronization symbol position {circumflex over (d)} 0 of one time slot of an initial update period; adjusting the synchronization symbol position according to an update period N track , and the step of adjusting the synchronization symbol position comprising: obtaining a synchronization symbol position {circumflex over (d)} k+1 of a corresponding time slot of a (k+1)th update period according to a synchronization symbol position {circumflex over (d)} k of a corresponding time slot of a kth update period and an inter-frame sampling derivation estimation value {circumflex over (T)} k of said kth update period according to the formula: {circumflex over (d)} k+1 ={circumflex over (d)} k +N track {circumflex over (T)} k ; wherein the corresponding time slot refers to a time slot corresponding to a position of said time slot of said initial update period; wherein an inter-frame sampling derivation estimation value {circumflex over (T)} k+1 of the (k+1)th update period is a weighted sum of the inter-frame sampling derivation estimation value {circumflex over (T)} k of the kth update period and an inter-frame sampling derivation track value {circumflex over (T)} track of the (k+1)th update period, and an initial inter-frame sampling derivation estimation value {circumflex over (T)} 0 is obtained by capturing the inter-frame sampling derivations; the inter-frame sampling derivation track value {circumflex over (T)} track of the (k+1)th update period is obtained by: estimating the synchronization symbol position of the initial time slot of each frame in the (k+1)th update period, making the subtraction to obtain the inter-frame sampling derivation of each adjacent frames, and obtaining the inter-frame sampling derivation track value {circumflex over (T)} track of the (k+1)th update period according to the inter-frame sampling derivation of each adjacent frames; obtaining synchronization symbol positions of other time slots in said kth update period according to the synchronization symbol position {circumflex over (d)} k of the corresponding time slot of the kth update period and the inter-frame sampling derivation estimation value {circumflex over (T)} k of said kth update period, wherein the inter-frame sampling derivation estimation value {circumflex over (T)} k refers to an estimation value of a synchronization symbol position derivation in one frame, k≧0; so as to implement a timing synchronization.
