Disclosed are a synchronization estimation method and a receiving end device, which are used for solving the problems of poor performance and relatively high noise of the existing synchronization estimation, and low accuracy and relatively high noise of the existing frequency offset estimation method. The method comprises: receiving a data sequence containing a preamble; and according to a long preamble in the preamble, conducting timing estimation and/or frequency offset estimation, so as to realize synchronization with a sending end, wherein the long preamble comprises a prefix, a long sequence and a suffix in sequence, wherein a sequence in the prefix is the same as a sequence in the long sequence which is separated from the prefix at a first set distance, and a sequence in the suffix is the same as a sequence in the long sequence which is separated from the suffix at a second set distance. |
