摘要：

Due to the rapid development in the field of communication today, carrier synchronization module in the receiver needs shorter lock-in time and better performance. The tradition method is hardly to meet the requirements. In this paper, by studying the earlier algorithm, we find open-loop algorithm and closed-loop algorithm have their respective advantages in the initial carrier synchronization and the track stage. Hence an algorithm combines the open-loop and closed-loop is proposed. Its performance is computed in the presence of the noises with different equivalent signal noise rate. It is also demonstrated more superiority than the tradition method.
