Patent ID: 8520783

Claim:
A receiving device comprising: a receiver that receives a frequency multiplex signal; a first Fourier transformation unit that transforms the received frequency multiplex signal to frequency domain signal on the basis of a window that specifies a time zone of Fourier transformation; a first time-domain waveform generator that generates a first time-domain waveform by performing inverse Fourier transformation of a plurality of pilot signals which are inserted into the frequency multiplex signal at fixed frequency intervals; a second time-domain waveform generator that generates a second time-domain waveform having an aliasing period which is longer than an aliasing period of the first time-domain waveform on the basis of the received frequency multiplex signal; a second Fourier transformation unit that synthesizes the first time-domain waveform to the second time-domain waveform and transforms the synthesized time-domain waveform to frequency-domain information; and a propagation-path compensation unit that compensates a propagation-path of the frequency multiplex signal which is output from the first Fourier transformation unit in accordance with information transformed by the second Fourier transformation unit.
