Abstract
An information processor has a CIR estimator configured to estimate channel impulse response of an input signal including a channel estimation sequence and a data sequence, based on the channel estimation sequence, an extended CIR calculator configured to calculate extended channel impulse response based on the channel impulse response estimated by the CIR estimator so that an extended CIR element padded with zeros is repeated a plurality of times in the extended channel impulse response, a Fourier transformer configured to convert the data sequence of the input signal into a frequency domain signal to calculate frequency response based on the extended channel impulse response, and an equalizer configured to perform equalization for removing a distortion from a propagation channel, based on the frequency domain signal and the frequency response.
