MULTICARRIER SIGNAL RECEIVING APPARATUS AND MULTICARRIER SIGNAL TRANSMITTING APPARATUS

摘要

A multicarrier-signal receiving apparatus includes: a Fourier-transformer that performs a Fourier transform on reception signals to extract subcarriers; a channel estimator that performs channel estimation on one of the extracted subcarriers using channel estimation symbols included in a subcarrier group to which the one of the extracted subcarriers belongs, the subcarrier group including subcarriers to which an identical phase rotation is added upon transmission; and a channel compensator that performs channel compensation on data symbols included in the one of the extracted subcarriers using a result of the channel estimation performed by the channel estimator on the one of the extracted subcarriers.
