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.

Abstract: One coding method is selected from a plurality of coding methods per data symbol group, an information sequence is encoded by using the selected coding method. The plurality of coding methods includes at least a first coding method and a second coding method. The first coding method is a coding method with a first coding rate for generating a first codeword as a first encoded sequence by using a first parity check matrix. The second coding method is a coding method with a second coding rate different from the first coding rate and obtained after puncturing processing, where a second encoded sequence is generated by performing the puncturing processing on a second codeword by using a second parity check matrix different from the first parity check matrix. A number of bits of the first encoded sequence is equal to a number of bits of the second encoded sequence.

Abstract: A decoding device includes: a BP decoder that performs BP decoding on an input signal; a maximum likelihood decoder that performs maximum likelihood decoding on a signal subjected to the BP decoding; and a selector that selects one of the input signal, the signal subjected to the BP decoding, and a signal subjected to the maximum likelihood decoding. In a configuration of the decoding device, when a decoder is appropriately operated according to quality of data, a calculation scale can be reduced, and power consumption can be decreased.
