卡尔曼滤波算法与Bootstrap算法比较

摘要

在信息化时代,人们对时间同步的精度要求越来越高.从时钟根据它和主时钟的偏差进行估计和调整,从而实现同步.在多个晶振的条件下,可以通过卡尔曼方法实现数据融合,通过卡尔曼滤波算法和Bootstrap算法对时钟进行校正,对偏差进行估计.该方法可以提高本地时间稳定性和准确性.%In the information age, the users has higher requirement for the accuracy of time syn-chronization.The slave clock achieves clock synchronization according to the offset of the slave clock and the master clock to estimate and adjust the offset.Under the condition of multiple crys-tal scillator, data fusion can be realized through Kalman filtering method.The clock correction and the deviation estimation were performed through Kalman filter algorithm and the Bootstrap al-gorithm.This method can improve the local time's stability and accuracy.
