PROBLEM TO BE SOLVED: To solve a problem that proper equalization processing can not be applied due to noises included in a pilot signal. SOLUTION: A signal equalization apparatus disclosed herein acquires a signal including the pilot signal, acquires a plurality of pilot signals transmitted at the time different from the transmission time of the signal above, acquires a delay profile in the pilot signals above, acquires a profile by each delay time in the delay profiles and eliminates noise in conformity with time change characteristics of its amplitude component and its phase component, estimates a pilot signal on the basis of the delay profiles from which the noise is eliminated, and equalizes the signal on the basis of the estimated pilot signal.
