摘要： A method of low latency encoding of an input bit sequence (S0) to yield an encoded bit sequence (S), and a corresponding decoding method, said encoding method including: a first encoding step (E1) applied to bits of the input bit sequence (S0), using a first code; an interleaving step (E3) in which an interleaver interleaves the bits obtained from said first code; and a parity, second encoding step (E4) applied to the bits obtained from said interleaver, using a second code, to generate said encoded bit sequence (S). The parity, second encoding step (E4) starts after a predetermined number Δ of bits have been interleaved, said predetermined number Δ of bits ranging between a first lower number Δi of bits depending on one or more parameters of said interleaving step (E3) and a first higher number Δs of bits corresponding to the total number of bits to be processed during said interleaving step (E3).

摘要： The invention relates to correcting codes for encoding and decoding a data signal. A signal including data variables is coded into a signal including the data variables and parity variables. The encoding and decoding operations are based on a parity check matrix comprised of a systematic matrix and a parity matrix and having rows corresponding coefficients of parity equations and distributed into decoding windows of same size. In order to increase convergence of the iterative decoding, the elements of at least one column of the systematic matrix associated with a decoding window are “0s”, except for a single element which is a “1”. A data variable is only involved in one equation of the window and not involved in solving the equations of other windows as long as the solving of equations of the window is not achieved.
