摘　　要：介绍了跳频通信系统同步方法和同步过程,并阐述了自相关同步法实现跳频通信系统同步捕获和同步跟踪的原理,着重讨论了基于最大似然准则,对时间和频率同步跟踪分别采用时间平分法和频率替换法求取同步估计值的方法,给出了原理框图、公式推导以及实验仿真结果,并对实验仿真结果进行了性能分析。实验仿真结果与性能分析表明该同步跟踪方法简单可行。This paper mainly introduces the synchronization methods and the procedure, and the primciple of acquisition and tracking in a FH/MFSK communication system with autocorrelation synchronization, and discusses the synchronization estimator in time and frequency using the techniques of dividing time averagely and displacing frequency which are based on maximum-likelihood, and lists the theory map, formula derivation, experimental simulation results and performance analyses. The experimental simulation results and performance analyses denote that the method is simple and possible.
