A method of estimating a coarse frequency offset in a receiver includes providing at least one candidate frequency offset in Orthogonal Frequency-Division Multiplexing (OFDM) symbols having transmission and multiplexing configuration control (TMCC) bins and auxiliary channel (AC) bins, modulating the TMCC bins and AC bins using differential binary phase shift keying (DBPSK) modulation, estimating a phase difference between a first symbol and a second symbol for the candidate frequency offset of the TMCC and AC bins to obtain a resulting phase difference, correcting the resulting phase difference based on a difference between the candidate frequency offset and a Fast Fourier Transform (FFT) center bin to obtain a corrected phase difference, mapping the corrected phase difference to numeric numbers, and adding the numeric numbers for the candidate frequency offset to obtain a summation result. The numeric numbers correspond to at least one of +1 or -1.
