接收机码元同步算法的研究

Survey on timing recovery method in digital receivers

对一种码元同步方法的整个环路进行了研究和仿真分析。这个系统环路由插值滤波器、gardner定时误差估计模块、NCO控制器以及环路滤波器等几个部分组成,文中对各个部分进行了分析并介绍其实现方法。最后在simulink下仿真实现,整个环路工作状况良好。

This paper described.a useful method of timing recovery in digital receivers. The loop of this method mainly includes interpolator, NCO control, timing error test and loop filter, resample. According to the algorithm, simulation results in simulink prove that the loop is effective.
