COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD
First Claim
1. A communication apparatus comprising:
- a deinterleaver setting, as an input, a third error-correction-code sequence obtained by rearranging bit positions of a second error-correction-code sequence in which two or more terminated first error-correction-code sequences are repeated from the terminated first error-correction-code sequences in accordance with a first rule, and rearranging bit positions of an input third error-correction-code sequence in accordance with a second rule that is different from the first rule to configure a fourth error-correction-code sequence including one or more of the terminated first error-correction-code sequences; and
an error corrector that performs error correction based on the fourth error-correction-code sequence, whereinthe second rule used by the deinterleaver is to extract bits capable of configuring the fourth error-correction-code sequence in order from a head of the third error-correction-code sequence.

Abstract
A communication apparatus includes a deinterleaver and an error corrector. The deinterleaver sets, as an input, a third error-correction-code sequence obtained by rearranging bit positions of a second error-correction-code sequence in which two or more terminated first error-correction-code sequences are repeated from the terminated first error-correction-code sequences in accordance with a first rule. The deinterleaver rearranges bit positions of the third error-correction-code sequence in accordance with a second rule that is different from the first rule to configure a fourth error-correction-code sequence including one or more of the terminated first error-correction-code sequences. The error corrector performs error correction based on the fourth error-correction-code sequence. The second rule used by the deinterleaver is to extract bits capable of configuring the fourth error-correction-code sequence in order from a head of the third error-correction-code sequence.
