Abstract: PURPOSE: A synchronization apparatus for precisely decoding the reception signal within a phase jitter modulation tag and a tag including the same are provided to determine the decoding starting point of payload data by using a MFM(Modified Frequency Modulation) flag and a correlator. CONSTITUTION: A plurality of correlators(120, 150, 170) implements a correlation calculation for a reception signal which is phase jitter modulated with a template of an internal match filter having the same shape with a part of the frequency modulation flag. An optimal signal selector(100) divides the signal received through a single path into various paths.
