The rapid development of information technology is promoting people's strong demand for perfect efficient digital communication system. Offset Quadraphase Shift Keying modulation technology is a constant-envelope digital modulation technology, which is the improved QPSK[1]. It overcomes the 180° phase jump of OQPSK, which has more advantages, such as fast power descent, low sidelobes and high spectrum efficiency, ect. Synchronization technology play a key role in high effectiveness of digital communication system. As the communication technology is developing continuously, the requirement is higher and higher in synchronization. So the research of synchronization is a wide attentive focus.
