摘要：
A synchronization signal detector includes: a first circuit configured to delay the data signal by a period of at least one data segment of the data signal to generate a delayed signal; a second circuit configured to produce a plurality of similarity signals according to the data signal and the delayed signal, each of the similarity signals representing the similarity between the data signal and the delayed signal, and a third circuit configured to determine the synchronization signal of the data signal according to the similarity signals. The present invention further provides a method corresponding to the signal detector.
