摘      要：In this paper, an iterative carrier recovery algorithm of Gaussian filtered minimum shift keying （GMSK） in burst-mode was designed. The data utilization rate and precision of the traditional demodulation method for recovering carrier signal in burst data packet with limited-length is poor. In order to solve this problem, this paper proposed an iterative carrier recovery algorithm. This algorithm can improve the estimated precision of carrier recovery and data utilization rate of burst data packet in a large extent by performing multiple forward and backward iterations. And the algorithm can be implemented in Simulink environment. As the communication mode of automatic identification system （AIS） is abrupt, the algorithm is especially suitable for satellite-based AIS.
