TRANSMISSION DEVICE, RECEPTION DEVICE, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

A coding scheme is selected from multiple coding schemes including at least a first coding scheme and a second coding scheme, an information sequence is encoded using the selected coding scheme, and the encoded sequence obtained by performing predetermined processing is modulated and then transmitted. The first coding scheme is a coding scheme having a first coding rate wherein a second codeword generated using a first parity check matrix is subjected to puncturing processing to generate a second encoded sequence, and the second coding scheme is a coding scheme having a second coding rate wherein a second codeword generated using a second parity check matrix different from the first parity check matrix is subjected to puncturing processing to generate a second encoded sequence, the second coding rate being different from the first coding rate and obtained after the puncturing processing. The number of bits of the first encoded sequence is equal to the number of bits of the second encoded sequence.
