摘要
Gardner算法是由Gardner提出的一种时间误差检测算法,可运用于全数字时钟同步电路。该文首先阐述了算法原理,然后利用MATLAB工具,对采用Gardner算法的时钟同步电路进行闭环仿真和开环仿真。仿真结果验证了Gardner算法的有效性,以及影响时钟同步性能的主要参数。
Introduced by Gardner,Gardner arithmetic is a timing error detector arithmetic,and could be applied to digital timing recovery cycle.At first,the paper states the principle of the arithmetic,and precedes the closed-cycle and open-cycle simulation with MATLAB.The result shows that the Gardner arithmetic is suitable for timing recovery cycle,and finds out the main parameter affecting the performance of the timing recovery cycle.
