Claim:
1. A transmission device comprising: a bit coding device configured to create a coded bit sequence by performing error correction coding on an input bit sequence, the bit coding device comprising: a coding circuit configured to create a first bit sequence by performing the error correction coding on the input bit sequence; an extraction circuit configured to extract a second bit sequence from the first bit sequence; and an information compression circuit configured to create a third bit sequence by performing lossy compression on the second bit sequence, wherein coded bits of the coded bit sequence include at least a portion of the third bit sequence; a modulation circuit configured to create a modulation symbol sequence that corresponds to the coded bit sequence; a transmission circuit configured to transmit a signal based on the modulation symbol sequence; and a compression control circuit configured to determine a ratio of a bit number of the third bit sequence that the bit coding device includes in the coded bit sequence, with respect to a bit number of the input bit sequence, depending on a coding rate used by the bit coding device or a modulation method used by the modulation circuit.
