PROBLEM TO BE SOLVED: To attain a solution of the problem that there is an interference wave component that cannot be corrected in the prior art. SOLUTION: A signal containing pilot signals is acquired, a plurality of pilot signals transmitted at different times are acquired from the signal, and a delay profile for the plurality of pilot signals is acquired. On the basis of the delay profile and the signal, a delay wave for a desired wave of each of sub carriers in the signal is acquired and on the basis of the delay profile, deviation of frequency in the delay wave from the desired wave is acquired. An interference amount, to each sub carrier, caused by the delay wave in which the acquired frequency deviation occurs, is acquired by a sum of interference amounts caused by a plurality of delay waves distributed in a predetermined frequency domain around the frequency of each of the sub carriers, and a signal subtracting the acquired interference amount from each sub carrier desired wave is demodulated.
