Abstract: PROBLEM TO BE SOLVED: To improve a precision in estimating channels, even if fluctuations among sub-carriers are large in wireless transmission path.
SOLUTION: A channel estimating device 16 uses a pilot symbol on an OFDM signal to individually acquire a channel estimation result for each of a plurality of sub-carriers, based on its amplitude/phase characteristics. A smoothing device 18 adds a unit channel estimation value of a sub-carrier, a unit channel estimation value of an adjoining sub-carrier on a high-range side, and an adjoining unit channel estimation value on the low-range side together. The amplitude correction value and phase collection value for correcting a transmission path distortion are generated, by acquiring an average value of the added values. At a correcting device 17 each sub-carrier of the reception signal is multiplied by the amplitude correction value and the phase correction value, for amplitude correction and phase correction with each sub-carrier.
