用内插实现定时功能。算法中有一些不足，但可以作为一个参考。-Using interpolation to achieve timing. Algorithm has some deficiencies, but can be used as a reference.

单载波定时同步经典程序，采用gardner定时误差检测，以及内插滤波器-Single-carrier timing synchronization classic program, gardner timing error detection, and the interpolation filter

Skew detection and correction is very important task before pre-processing of an image and it is a major problem in scanned documents, if it not detected correctly it will lead wrong result in future during image analysis. During the scanning of th

接收端时间同步环仿真，包括插值滤波器、环路滤波器、GARDNER算法以及数字控制振荡器(Receiver time synchronization loop simulation, including interpolation filter, loop filter, GARDNER algorithm and digital controlled oscillator)
