<p><P>PROBLEM TO BE SOLVED: To eliminate errors between a phase and amplitude caused by fraction deviation less than one sample of a DFT window. <P>SOLUTION: A receiving device converting a received time-domain signal into a plurality of frequency-domain signals, has: a discrete Fourier transformation part performing discrete Fourier transformation of a discrete time-domain signal in a discrete Fourier transformation window among discrete time-domain signals obtained by sampling the time-domain signal at a predetermined sampling rate to generate the frequency-domain signals corresponding to a plurality of sub carriers; and a correction part correcting the plurality of frequency-domain signals respectively on the basis of a phase fluctuation amount and an amplitude fluctuation amount that are caused by fraction deviation less than one sample of a discrete Fourier transformation window and depend on a fraction deviation amount and an order of the sub carriers. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
