PROBLEM TO BE SOLVED: To perform adaptive transmission path estimation even in a radio environment having a high fluctuation frequency.SOLUTION: An equalization device 100 includes: a transmission path characteristic division section 130 for dividing a first transmission path characteristic into components of a plurality of domains corresponding to a plurality of first intervals on a fluctuation frequency axis, respectively, and to a plurality of second intervals on a delay time axis, respectively; a desired component extraction section 140, 150 for extracting desired components by determining symmetry of the distribution of the divided components with a symmetry axis on a delay time axis assuming a predetermined fluctuation frequency; a transmission path characteristic combination section 160 for combining the extracted desired components to generate a second transmission path characteristic; and an equalization section 170 for performing equalization by using the second transmission path characteristic. |
