Abstract

A receiver includes a detector to detect an interfered-with carrier from a received and demodulated signal, a fast Fourier transform computation part to perform fast Fourier transform to convert a time domain signal to a frequency domain signal and adjust an output power level of a desired carrier wave contained in the frequency domain signal based upon the detected interfered-with carrier, and a channel estimation part to estimate a channel characteristic based upon a non-interfered-with pilot signal that is not subject to influence of the interfered-with carrier and an interpolation value interpolated based upon the non-interfered-with pilot signal, the non-interfered-with pilot signal being obtained by removing, based upon the interfered-with carrier, an interfered-with pilot signal that is subject to the influence of the interfered-with carrier and an interpolation value interpolated based upon the interfered-with pilot signal.
