<P>PROBLEM TO BE SOLVED: To provide an OFDM communication apparatus of high efficiency which attains high transmission power at low cost. <P>SOLUTION: A transmitter includes a PAPR calculating section 6 for calculating PAPR information S3 of the time waveform, by each of plural OFDM symbols; a power correction means for correcting average power by each plural OFDM symbols, on the basis of the PAPR information S3; a notification information generating section 8 for generating a piece of notification information S6 for notifying a receiver of the average power correction value S4 for each plural OFDM symbols; and a transmission means for transmitting notification information S6 from a transmission antenna 12 to a receiving antenna. The receiver includes a receiving means for acquiring a reception signal from the transmitter via the receiving antenna; and a reference information calculation section for acquiring an average power correction value every plurality of OFDM symbols on the basis of the notification information included in the reception signal, correcting the reception signal, on the basis of the acquired average power correction value, and calculating reference information for recovering information regarding each subcarrier. <P>COPYRIGHT: (C)2011,JPO&INPIT |
