FAST ENCODING AND DECODING METHODS AND RELATED DEVICES

摘要

The invention concerns a method for low latency encoding of an input bit sequence (SO) into an encoded bit sequence (S) and a corresponding decoding method, said encoding method including a first encoding step (E1) applied on bits of the input bit sequence (SO), based on a first code; an interleaving step (E3) for interleaving, with an interleaver, the bits derived from said first code; a second so-called parity encoding step (E4), applied to the bits derived from said interleaver, based on a second code, to generate said encoded bit sequence (S). The method is characterized in that said second parity encoding step (E4) starts after the interleaving of a predetermined number ? of bits, said predetermined number ? of bits ranging between a smaller number ?i of bits depending on at least one parameter of said interleaving step (E3), and a first greater number ?s of bits corresponding to the total number of bits to be processed during said first interleaving step (E3)
