PROBLEM TO BE SOLVED: To provide a method of transmitting an orthogonal frequency division multiplexing signal wherein high accuracy correction of the fluctuation in a receiving level and/or frequency band is achieved, so that there occur no detection errors in the demodulated data, and a receiver thereof. SOLUTION: The orthogonal frequency division multiplexing signal transmitted from a transmitting side to a receiving side intermittently includes a particular symbol SO having a predetermined pattern in addition to a symbol Sm including the data to be transmitted. At the receiving side, the fluctuation in the receiving level and/or the fluctuation in the frequency band of the received signal are detected and corrected. Since the particular symbol SO has a particular pattern, the fluctuation in the receiving level and/or the fluctuation in the frequency are strongly correlated with the fluctuation in the receiving level and/or the frequency band of the received signal. Therefore, the fluctuation in the receiving level and/or the fluctuation in the frequency band of the received signal are accurately detected from the particular symbol SO, so that high accuracy correction is achieved.
