Claim Text:
1. A transmission signal generation device, comprising: an encoder configured to generate a first bit sequence that is an N-bit codeword from a K-bit information bit sequence, where K and N are each an integer greater than or equal to 1; a bit adjuster configured to (i) judge whether or not to add a known bit sequence to the first bit sequence, and (ii) when judging negatively, output the first bit sequence, and when judging affirmatively, output a second bit sequence that is obtained by adding the known bit sequence to the first bit sequence; and a mapper configured to modulate the first bit sequence of N bits or the second bit sequence using a modulation scheme selected from among a plurality of modulation schemes, wherein a modulation symbol of the selected modulation scheme has X bits, where X is an integer greater than or equal to 1, when N is an integral multiple of X, the bit adjuster does not add the known bit, and when N is not the integral multiple of X, the bit adjuster adds the known bit of α×X−N bits to the first bit sequence, where α and α×X−N are each an integer greater than or equal to 1.
