摘要： The present invention discloses a fine frequency offset estimation method and apparatus. The method comprises: calculating a first accumulated estimation value corresponding to a first multiframe state according to a phase relevant value of a subframe and a phase of a subframe in the first multiframe state; calculating a second accumulated estimation value corresponding to a second multiframe state according to the phase relevant value of the subframe and a phase of a subframe in the second multiframe state; determining that a decision result of a multiframe state is the first multiframe state or the second multiframe state according to the first accumulated estimation value and the second accumulated estimation value; and performing a fine frequency offset estimation according to the decision result of the multiframe state. The apparatus disclosed in the present invention is less coupled with other modules, has excellent performance in various environments, and realizes the unbiased estimation of timing offset.
