Abstract设计了一种适用于全数字接收机的新型位同步系统,该系统由插值滤波器、Gardner定时误差检测单元、环路滤波器和NCO控制单元构成,相比以前的滤波法和添扣脉冲法具有同步建立时间短、保持时间长和适用范围广的优点。在matlab simulink下对整个系统进行仿真,证明其能纠正0.1%的定时频率偏差,性能良好。
Other Abstracta new symbol timing synchronization system for all digital receiver is designed, which is composed of interpolation filter, Gardner timing error detector unit, loop filter and NCO control unit.Compared to the traditional method of filtering or pulse add-subtracting, the method designed in this paper has the advantage of short synchronization set-up time, long hold-on time and wide application.The system is built and simulated with matlab simulink , which proves that it can correct 0.1% timing frequency errsor has good performance.
