摘要：
A data aid carrier synchronization scheme for high rate burst mode communication systems is present in this paper. Computer simulation results show that the scheme just spends 10 symbols for initial phase acquisition when SNR >= 8dB. In addition, by -pi/4 phase rotator, the normal QPSK phase tracking loop is suitable for pi/4-DQPSK. The proposed carrier synchronization scheme is suitable for digital implementation in burst communication systems.
