摘要： The disclosure describes an apparatus for correcting a frequency offset in a OFDM receiving system. The apparatus comprises a loop filter for receiving a predetermined phase value, multiplying the phase value by a gain value, accumulating the multiplied values, and outputting the accumulated value; a voltage control oscillator for multiplying the accumulated value outputted from the loop filter by the gain value, feeding back the result, and adding the feedback values; a derotator for obtaining sine and cosine waves from the result outputted from the voltage control oscillator, multiplying the obtained value by an output signal from an A/D converter, and outputting the multiplied value to an OFDM demodulator; a correlation calculation unit for calculating a correlation value from a value outputted from the OFDM demodulator; and a frequency offset estimator for generating a phase signal according to a frequency offset outputted sequentially within a predetermined frequency offset range, outputting the phase signal to the loop filter, determining an approximate value of the frequency offset within 1/4 range of a carrier frequency interval by using a value outputted from the correlation calculating unit for a corrected symbol, and correcting the frequency offset according to a final determined frequency offset estimation value.
