PROBLEM TO BE SOLVED: To make it possible to adaptively perform transmission path estimation even in radio wave environment where a fluctuation frequency is large.SOLUTION: An equalization device comprises: a transmission path characteristic division unit 130 for dividing a transmission path characteristic acting on a pilot carrier into components in a plurality of regions on two axes of a fluctuation frequency axis and a delay time axis; an SP transmission path characteristic distribution calculation unit 140 for calculating a physical quantities of the divided components of the plurality of regions; a desired transmission path characteristic distribution calculation unit 150 for calculating a physical quantity of a desired component including no unnecessary repeating component by using regularity with which pilot carriers are arranged and a statistical characteristic of a transmission path; and a desired transmission path characteristic extraction unit 160 for extracting a component of a region including the desired component from the divided plurality of regions on the basis of the calculated physical quantity of the desired component. |
