  • Patent number: 11936470
    Abstract: 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.

  • Patent number: 11923871
    Abstract: One coding scheme is selected from a plurality of coding schemes, an information sequence is encoded by using the selected coding scheme, and an obtained encoded sequence is modulated to obtain a modulated signal. The obtained modulated signal is subjected to a phase change and is transmitted. The plurality of coding schemes include at least a first coding scheme and a second coding scheme. The first coding scheme is a coding scheme with a first coding rate for forming a generated first codeword as a first encoded sequence by using a first parity check matrix. The second coding scheme is a coding scheme with a second coding rate obtained after puncturing processing, for generating a second encoded sequence by performing the puncturing processing on a generated second codeword by using a second parity check matrix different from the first parity check matrix. The number of bits of the first encoded sequence is equal to the number of bits of the second encoded sequence.
