ABSTRACT:
The present invention relates to an apparatus and method of compensating for a frequency offset in an orthogonal frequency division multiple access system that is capable of efficiently estimating and compensating for the frequency offset. A receiver of the orthogonal frequency division multiple access system can individually estimate a fractional frequency offset and an integer frequency offset by using a downlink preamble signal. Further, the receiver can compensate for the frequency offset by adding the integer frequency offset once after completely compensating for the fractional frequency offset. Therefore, it is possible to efficiently compensate for the frequency offset.
