Patent ID: 7372908

Claim:
A radio transmitting apparatus that transmits a multicarrier signal including a plurality of subcarriers, said radio transmitting apparatus comprising: a duplicating section that duplicates a bit sequence to generate a plurality of same bits; a modulating section that performs modulation to include each of the plurality of same bits to a different symbol; a generating section that allocates each of the symbols modulated by said modulating section to each of the subcarriers each having a different frequency to generate the multicarrier signal; and a transmitting section that transmits the multicarrier signal generated by said generating section, wherein: said duplicating section obtains N/M of the plurality of same bits, where M is the number of bits for one symbol in a reference modulation scheme, N is the number of bits for one symbol in a modulation scheme used in said modulating section, and N/M is an integer greater than one.
