PROBLEM TO BE SOLVED: To solve the problem that it is necessary to provide not simple circuit configurations but complicate circuit configurations in order to confirm the existence of an SFN wave by a receiver in a reception environment where the SFN wave exists, and it is necessary to spend huge manufacturing costs for its achievement. SOLUTION: This OFDM receiver is provided with a means for detecting the guard correlation of a main broadcast wave and a plurality of SFN to be transmitted by the same frequency, and for properly controlling FFT window position on the basis of the detected guard correlation, and for digitizing and outputting the FFT window position information acquired by those control and a means for calculating and displaying the output FFT window position information.
