The present invention relates to, by calculating the correlation value of the received signal and the code, or sequence, considering the length N of the code or sequence, N- point FFT on the calculated correlation value to the frame synchronization method of a frame synchronizer ( FFT: a Fast Fourier Transform) process by performing the operation generating the N correlation values, the generated N number of correlation values, the largest power, and the detected correlation value with the detected correlation value with a predetermined threshold value of the comparison, and determines whether or not acquired the synchronization of the frame, the N correlation values each, comprising the code, or sequence, the correlation between the value and the reception of the N calibration signals, respectively, the N-corrected received signals the received signal to N each other are generated by multiplying a different frequency offset value.
