Frequency offset estimation method and device

一种频偏估计方法及装置

Abstract

The present invention discloses a frequency offset estimation method. The method comprises a step of carrying out sliding window storage of maximum likelihood frequency offset estimations and obtaining a maximum likelihood frequency offset estimation set, and a step of using sliding filtering on the maximum likelihood frequency offset estimation set to combine, and obtaining a final maximum likelihood frequency offset estimation. The invention also discloses a frequency offset estimation device.
本发明公开了一种频偏估计方法,该方法包括:对最大似然频偏估计进行滑窗存储,获得最大似然频偏估计集;采用平滑滤波对最大似然频偏估计集进行合并,得到最终的最大似然频偏估计。本发明还同时公开了一种频偏估计装置。
