Abstract
A receiver that estimates a frequency response of a transmission path using a first pilot signal stored in advance and a second pilot signal received, the receiver includes an electric power information calculation means that calculates electric power information of the first pilot signal for each subcarrier, a coefficient calculation means that calculates a coefficient on the basis of comparison between the electric power information and a predetermined threshold, a multiplication means that multiplies the electric power information of the first pilot signal for each subcarrier by a corresponding coefficient calculated by the coefficient calculation means, a transmission path estimation means that calculates an estimation value of a frequency response of a transmission path on the basis of the first pilot signal multiplied in the multiplication means and the second pilot signal received from a transmitter, and an interpolation processing means that performs interpolation processing for the calculated estimation value.
