Classification: CPC H | IPC H

Claim 12:
13. A communication method comprising:
generating two codeword signals by encoding data;
generating a first mapping signal and a second mapping signal by mapping each of the two codeword signals on at least one of an in-phase quadrature phase (I-Q) plane corresponding to a quadrature phase-shift keying (QPSK) scheme and an I-Q plane corresponding to a 16 quadrature amplitude modulation (16QAM) scheme;
arranging the second mapping signal by using an equation having an angle that is not equal to zero;
combining the first mapping signal and the second mapping signal arranged using the equation to generate a combined signal; and
transmitting the combined signal from at least an antenna,
wherein a first codeword of the two codeword includes a first cyclic redundancy check (CRC) bits relating to the first codeword, and a second codeword of the two codeword includes a second cyclic redundancy check (CRC) bits relating to the second codeword, and
the combined signal transmitted from the antenna includes at least one data of the first codeword and one data of the second codeword on each symbol.
