Abstract
An integer frequency offset estimation scheme in an orthogonal frequency division multiplexing (OFDM)-based system is disclosed. A receiving apparatus for receiving a signal according to an OFDM includes an OFDM symbol acquisition module for acquiring at least two consecutive OFDM symbols, a symbol operation module for operating upon pilot symbols and/or data symbols belonging to frequency bands determined according to a plurality of candidates for integer frequency offsets among a plurality of pilot symbols and a plurality of data symbols included in the acquired OFDM symbols, and an integer frequency offset estimation module for selecting a final integer frequency offset among a plurality of candidates for integer frequency offsets according to magnitudes of operation values obtained by the symbol operation module, wherein the frequency bands determined according to the candidate for integer frequency offsets are obtained by frequency-shifting preset frequency bands at which all pilot symbols are transmitted according to the candidate for integer frequency offsets.
