摘要：A method and apparatus for frequency offset estimation exploits thedifferences in reference symbol timing for different channels to resolve ambiguities in
the frequency offset estimation. Based on the initial frequency offset estimates, ahypothesis table is constructed providing hypothesized frequency offsets for eachchannel for a plurality of possible offset regions. An error metric for each offset region iscalculated based on the difference of the hypothesized frequency offsets. The set ofhypothesized frequency offsets that minimize the error metric is selected as the finalfrequency offset estimates.
