A receiver performs an inverse Fast Fourier Transform (FFT) on a plurality of carriers to receive an Orthogonal Frequency Division Multiplexing (OFDM) signal to be transmitted by converting a signal along a frequency-domain into a signal along a time-domain. The receiver includes a frequency response acquisition section configured to acquire a frequency response from the received OFDM signal. The receiver also includes a smoothing section configured to produce a smoothed frequency response from the frequency response, a decimation section configured to decimate a number of points from the smoothed frequency response to produce a decimated frequency response including points corresponding to a path that is reached first, and a time response acquisition section configured to acquire a time response from the decimated frequency response including the points corresponding to the path that is reached first.
