Zusammenfassung:An OFDM modulation device (1) includes a communication use specifying unit (14) to specify a communication use of a communication frame, a header generating unit (15) to generate a header of the communication frame in which communication use specifying information indicating the communication use specified by the communication use specifying unit (14) is stored, a payload generating unit (16) to generate a payload of the communication frame, and an inverse fast Fourier transform unit (11) to generate a communication frame of time domain by executing an inverse fast Fourier transform of a size corresponding to the communication use specified by the communication use specifying unit (14) on data of frequency domain including the header generated by the header generating unit (15) and the payload generated by the payload generating unit (16).
