Error correction coding apparatus and error correction decoding apparatus

摘要

An error correction coding apparatus divides transmission information sequences in n subframes (n is an arbitrary natural number) into n1 subframes (n1 is a natural number<n) and n2 subframes (n2 is a natural number which satisfies n1+n2=n), block-codes the n1 subframes for every m1 subframes (m1 is a factor of n1) so as to generate a first error correction code, and block-codes the n2 subframes for every m2 subframes (m2 is a factor of n2) so as to generate a second error correction code.
