介绍两类同步方法都是采用滑动相关寻找峰值的办法，区别在于使用的相关器模板和先验信息。每种方法在具体实现上又可分为：串行搜索和并行搜索

通过滑动取相关值最后求最大值，找去最佳的样值抽样时刻，完成时间估计。这是一些基础的程序-Through the sliding value of the final order to check the relevant maximum, to the best kind to find the value of sampling time, the estimated completion time. These are the basis of the procedures
