Abrégé
(EN) The present invention involves padding the bit sequence in the first interleaver. The present method adds to an end of the bit sequence a sufficient number of padding bits L to permit modulus 16 operation of the bit sequence. After performing the interleaving, L bits are removed from an end of the interleaved sequence. This allows the interleaving to be performed in 16-bit segments simultaneously.
