[PROBLEMS] To prevent accuracy in estimation transmission characteristics even if a number of Fourier transform points in a symbol index direction is reduced. [MEANS FOR SOLVING PROBLEMS] A statistic power spectrum calculating part (28) calculates a statistic power spectrum distribution {km,n} based on two-dimensional Fourier transform data {hm,n}. A 2D filter circuit (23) selects and extracts a data group in a specific domain established based on a two-dimensional filter window calculated by a filter coefficient determination circuit (26) from the statistic power spectrum distribution {km,n}. A 2D inverse Fourier transform part (24) can generate the estimation transmission characteristics {gm,n} without degrading accuracy even if the number of Fourier transform points in the symbol index direction is reduced, for example.
