  • Publication number: 20010016931
    Abstract: The present invention concerns a digital transmission method of the error-correcting coding type which comprises, before a step of transmitting on a channel, a coding procedure comprising at least one puncturing step, and, after said transmission step, a decoding procedure comprising at least one depuncturing step, said coding procedure, applying a given coding scheme, generating a coded information item representing, with a certain redundancy, said useful information item and said decoding procedure estimating said useful information item by correcting transmission errors. According to the invention, this digital transmission method also comprises a step of observing the transmission conditions and a puncturing scheme selection step (2) for selecting, according to said at least one parameter, an optimum performance puncturing scheme amongst a plurality of predetermined puncturing schemes, the overall efficiency of said coding step and said puncturing step being a constant efficiency.

  • Publication number: 20010010089
    Abstract: A digital transmission method of the error-correcting coding type comprises a coding procedure before transmission and a decoding procedure for obtaining a correction of transmission errors. The said coding procedure comprises a plurality of elementary coding steps associated in parallel or in series. The decoding procedure is iterative and comprises, for each iteration, a plurality of elementary decoding steps (51, 52, 53) which correspond to the said plurality of elementary coding steps and which each generate at least one weighted output information item which can be transmitted to one or more other elementary decoding steps.
