摘要： A fine timing method is provided. The method comprises: calculating values of a first timing metric function based on cross-correlation between a received signal and M training sequences within a time period, to obtain a plurality of sets of X values spaced according to a certain pattern; calculating summations for the plurality of sets of X values, respectively; and determining the beginning of a data frame based on the calculated summations.
