Abstract
A frequency offset estimator () and corresponding method () provides a frequency offset estimate () for an OFDM signal. The estimator comprises a data parser () coupled to an input signal () and arranged to select a group of symbols (-) or corresponding samples corresponding to predetermined symbols from the input signal and a processor () arranged to provide a correlation corresponding to the symbols, where the correlation corresponds to a frequency offset estimation for the input signal and is determined in a sequential fashion so that the correlation is provided concurrently with the last symbol or sample of the group of symbols to be selected.
