Claim Text:
1. A transmission device comprising: an error correction encoder configured to generate a first encoded data sequence from an input data sequence using a first coding rate and a first code length, and generate a second encoded data sequence using a second coding rate and a second code length; a mapper configured to generate a first modulation symbol sequence by applying a first mapping pattern of a first modulation scheme to the first encoded data sequence, and generate a second modulation symbol sequence by applying a second mapping pattern of a second modulation scheme to the second encoded data sequence; and a transmitter configured to transmit the first modulation symbol sequence and the second modulation symbol sequence, wherein the mapper uses the first mapping pattern and the second mapping pattern that are different from each other for mapping, when (i) the first code length and the second code length are different from each other, (ii) the first modulation scheme and the second modulation scheme are the same in the number of transmission bits per symbol, and (iii) the first coding rate and the second coding rate are the same.
