PROBLEM TO BE SOLVED: To provide an equalization device capable of rightly correcting distortion of a received signal, an equalization method and a receiving apparatus.SOLUTION: An equalization device 1 and the receiving apparatus include: a known signal supply part 12 for supplying a known signal pn[k]; a correlation calculation part 11 for generating a correlation sequence (c) indicating a correlation between a received signal R0 and the supplied known signal; a discrete Fourier transformation part 13 for generating a discrete Fourier transformation result Fc by performing discrete Fourier transformation on the correlation sequence (c); an auto-correlation noise suppression part 14 for generating a transmission line estimation result Fh by multiplying the discrete Fourier transformation result Fc by an auto-correlation noise suppression coefficient G; and a distortion correction part 15 for correcting the distortion of the received signal R0 by using the transmission line estimation result Fh. The auto-correlation noise suppression coefficient Gis a coefficient which is calculated on the basis of an auto-correlation matrix W of the supplied known signal. |
