<p>An receiver apparatus according to an OFDM system includes a inter-symbol interference suppressing unit configured to modify to a predetermined content a portion of a dominant wave included in a received signal and to modify to a predetermined content a portion of at least one delayed wave included in the received signal, a tentative demodulation unit (201,202) configured to demodulate a signal inclusive of the modified dominant wave and the modified delayed wave or inclusive of the unmodified dominant wave and the modified delayed wave according to the OFDM system so as to output a tentatively demodulated target symbol, and an inter-carrier interference suppressing unit (802,804,806,808), wherein the inter-carrier interference suppressing unit includes a first unit (804) configured to further modify the modified portion of the modified delayed wave in response to the tentatively demodulated target symbol, a second unit (806) configured to further modify the modified portion of the modified dominant wave and the modified portion of the modified delayed wave in response to the tentatively demodulated target symbol, and a selecting unit (802) configured to select one of the first unit and the second unit in response to a delay profile.</p> |
