Abstract:
1. A radio communication apparatus comprising: a generating section configured to generate a bit sequence by forcibly setting each of at least the lowest two bits of a plurality of bits to a 1, the plurality of bits forming a modulation symbol in the bit sequence; and a modulating section configured to modulate the bit sequence by mapping the plurality of bits on a single modulation mapper, wherein the single modulation mapper has 16 first signal points for 16 QAM, wherein said generating section forcibly sets each of the lowest two bits of the plurality of bits to the 1 in a way that the plurality of bits are mapped to one of second signal points, which are a part of the first signal points, a distance between the second signal points being equivalent to the largest distances existing among the first signal points in an I-Q plane of the single modulation mapper.
