Abstract:
1. 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, comprising: an electric power information calculator that calculates electric power information of the first pilot signal on a subcarrier basis; a coefficient calculator that calculates a coefficient corresponding to a subcarrier on the basis of comparison between the electric power information calculated by the coefficient calculator and a predetermined threshold; a multiplier that multiplies a signal component of the first pilot signal corresponding to each subcarrier by the coefficient corresponding to each subcarrier; a transmission path estimator that calculates an estimation value of a frequency response of a transmission path on the basis of the first pilot signal multiplied in the multiplier and the second pilot signal received from a transmitter; and an interpolator that performs interpolation processing for the estimation value calculated.
