| 摘 要： | 在20 ns低抖动的无线同步脉冲传输的试验中，发现包络检波的解调方法虽可以完成脉冲传输功能，但是由于接收功率的变化，会造成脉冲抖动。采用自动控制理论中比例-积分-微分(PID)控制方法实现自动增益控制，令检波功率趋于稳定，进而减小脉冲抖动。通过仿真验证了本文方法的有效性。

| Abstract: | During the experiment of pulse propagation with a jitter under 20 ns, it is found that even though the envelope demodulation method for detection of pulse can work, the changes of received power would cause pulse jitter. In order to reduce the pulse jitter, the Proportional Integral Derivative(PID) control method is adopted to realize the automatic gain control and therefore ensure the power stability. The effectiveness of the proposed method is verified through simulation. |
