Patent ID: 8315318

Claim:
An OFDM signal transmitting apparatus configured to transmit an OFDM signal, the OFDM signal transmitting apparatus comprising: an encoder section configured to perform coding processing on data in a unit of a coding block; an interleaving section configured to perform interleaving processing on the data of which the coding processing has been performed in the encoder section, in a unit of an interleaving block; and an OFDM signal generator section configured to perform processing of generating an OFDM signal by use of data included in the interleaving block on which the interleaving processing has been performed, and to transmit the OFDM signal thus generated, wherein the interleaving block is a part of a transmission time interval block including data to be transmitted in a transmission time interval and a coding block obtained after coding, and the OFDM signal generator section maps the data included in the interleaving block in the order from a sub-carrier at a lower frequency side, and when mapping of the data included in the interleaving block is ended at a particular sub-carrier in the middle, starts mapping data included in a next interleaving block, for an identical OFDM signal receiving apparatus, for a sub-carrier at a higher frequency side of the particular sub-carrier in the middle.
