Abstract
A transmission device has an inverse fast Fourier transform converter (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 (second circuit) that shifts frequency of the waveform data generated by the inverse fast Fourier transform converter.
