| 摘 要： | 针对载波同步的两个关键问题———提高速度和适应多模式,研究了锁相环的鉴频辅助方法,构建了基于Costas鉴相和点积、差积鉴频算法的环路。仿真结果表明,所研究的载波同步方法适应BPSK、QPSK和8PSK等调制方式,同步速度约为传统方法的2倍。

| Abstract: | Aiming at the two key points in carrier synchronization,accelerating synchronization and adapting to multi-mode,the method of frequency-detecting aid of phase-locked loop(PLL) is studied,the loop based on Costas and Dot,Cross algorithm is constructed.The simulation result shows that the carry synchronization method in this paper can adapt to BPSK,QPSK,8PSK mode and so on,and the synchronization speed is about 2 times that of the traditional way. |
