Abstract:
A transmission device 100 has an inverse fast Fourier transform converter 104 (first circuit) that acquires plural multi-value symbol data each of which is assigned to a dedicated subcarrier, and generates waveform data on the basis of the acquired plural multi-value symbol data, and a digital frequency converter 107 (second circuit) that shifts frequency of the waveform data generated by the inverse fast Fourier transform converter 104.
