Interleaving method and communication device

摘要

An interleaving method according to the present invention is an interleaving method implemented when interleaving is performed on an encoded sequence after being error-correction encoded in a communication device on a data transmission side. This method is implemented in such a manner that an inter-carrier interleaver (6) rearranges carrier numbers according to an error correction method, and separates the encoded sequence after being error-correction encoded by each number of bits corresponding to a modulation method obtained for each carrier, and that an inner-carrier bit interleaver (5) rearranges bits by the number of bits separated according to the modulation method.
