ESTIMATING METHOD, SAMPLING FREQUENCY OFFSET CALCULATING METHOD, AND PHASE ESTIMATING METHOD AND DEVICE

摘要

An estimating method for estimating a phase difference of two frames is provided. The estimating method includes: providing a first sequence according to a header of a first frame; providing a second sequence according to a header of a second frame, wherein the first and second frames are successive frames, and the first and second sequences are pseudo noise sequences; performing a correlation calculation according to the first and second sequences to generate a plurality of correlation values; and estimating the phase difference between the first and second frames according to the correlation values.
