  • Error-correction coding method comprising local error detection codes interconnected by state words, corresponding decoding method, transmitting, receiving and storage devices and program
    Patent number: 7836384
    Abstract: A coding method is provided for associating redundant and source data and for carrying out a plurality of local codes associating at least one input status word and at least one output status word according to at least one label word and permutations applicable on at least certain of said words. The local codes are embodied in the form of detection codes and not error correction codes on a predetermined coding alphabet. The local codes are interconnected by the status words in such a way that at least one coding matrix is formed, each of which defining a base code.
    Type: Grant

  • Error correction coding method using at least twice a same elementary code, coding method, corresponding coding and decoding devices
    Patent number: 7392455
    Abstract: The invention relates to an error correction coding method, using at least two distinct sections of a predetermined elementary code, associating an arrival vector (s2, s3) with a starting state vector (s0, s1), according to a vector of branch labels (b0, b1, b2, b3), defining a code word, two sections of said elementary code being distinct when the order and/or the role of the elements of said branch label vector are changed.
