RECEPTION DEVICE AND RECEPTION METHOD

摘要

It is possible to reduce the affects of an interference signal while suppressing increase of the circuit scale and the processing time.  A reception device receives a multicarrier signal and an interference signal via a radio transmission path and detects a frequency position of the interference signal.  Filtering is performed to suppress the multicarrier signal and the interference signal at the detected frequency position of the interference signal.  A guard interval is removed from the multicarrier signal after suppressed by the filtering.  After modulating each of the subcarriers of the multicarrier signal from which the guard interval has been removed, the demodulated signal is subjected to an error correction.
