摘要 |
An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2. A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved. |

1. A data processing scheme comprising:
an encoding step of outputting a first bit sequence that is an N-bit codeword from a K-bit information bit sequence; a mapping step of generating a first complex signal s1 and a second complex signal s2 with use of a bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2; and a bit length adjustment step of, after the encoding step and before the mapping step, performing bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputting the first bit sequence after the bit length adjustment as the second bit sequence. |
