Abstract: The present invention provides a method for coarse frequency synchronization in an OFDM receiver. Even if the maximum variation of crystal oscillator (X-TAL) frequency disturbance is maximized and most of the variation in crystal oscillator (X-TAL) frequency disturbance is vary small, the estimation or search method of the present invention is capable of rapidly and effectively terminating the estimation of the integral multiple frequency offset (IFO). The integral multiple frequency offset (IFO) candidate is ascendingly increased and descendingly reduced at one value interval. In the estimation IFO, the correlation peak value in the intermediate status is compared to the thresholds, the coarse frequency synchronization (CFS) acquisition directly is ended and ensured when the correlation peak value is greater than the threshold, and a confidence check is not performed when correlation peak value is less than the threshold for considerably reducing the acquisition time of the CFS.
