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.

Abstract: PURPOSE: A correlator used in a phase jitter modulation of a demodulation apparatus is provided to obtain an optimal performance in a BER(bit error rate) view point by considering a phase jitter modulation property. CONSTITUTION: A correlator(100) comprises a template(110) and an extractor(120). The template has a set value of a standard sampling about the modulated signal of a phase jitter modulation system. An extractor extracts a consistency rate value which expresses the degree of the consistency by comparing the modulation signal of a sampled phase jitter modulation method.
