PROBLEM TO BE SOLVED: To provide a communication device and a communication system capable of demodulating data rapidly.SOLUTION: A communication device includes a deinterleaver and an error corrector. A third error correction code sequence obtained by rearranging the positions of bits according to a first rule for a second error correction code sequence, repeating more than one terminated first error correction code sequence, across a plurality of terminated first error correction code sequences, is inputted to the deinterleaver. The deinterleaver constitutes a fourth error correction code sequence including the terminated first error correction code sequence, by rearranging the positions of bits according to a second rule different from the first rule for the third error correction code sequence. The error corrector performs error correction based on the fourth error correction code sequence. The second rule of the deinterleaver is to extract the bits, that can constitute the fourth error correction code sequence, sequentially from the head side of the third error correction code sequence.SELECTED DRAWING: Figure 1 |
