Publication number: 20240243834Abstract: 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.Type: ApplicationFiled: January 25, 2024Publication date: July 18, 2024Inventors: Yutaka MURAKAMI, Tomohiro KIMURA, Mikihiro OUCHI
