Claim 22:
23. The decoding method according to claim 21, wherein
the polar code is a systematic polar code or a non-systematic polar code,
the decoding method includes:
a systematic polar processing of performing decoding processing of a systematic polar code when a systematic polar code is decoded; and
a selecting of inputting a processing result in the systematic polar processing to the decoded bit selecting when a systematic polar code is decoded, and inputting the decoding candidates selected in the decoding candidate selecting to the decoded bit selecting when a non-systematic polar code is decoded, and
the systematic polar processing includes:
a second bit arrangement changing of generating a second bit sequence of the first code length by arranging the decoding candidates corresponding to the second code length selected in the decoding candidate selecting at positions same as positions where the decoding candidates are arranged in the first bit arrangement changing;
a second polar encoding of performing polar encoding on the second bit sequence; and
a thinning processing of selecting a code word of the second code length from a result of encoding in the second polar encoding.
