Patent ID: 7027521

Claim:
Digital transmission method comprising: coding, from a useful information item, a coded information item comprising the useful information item and at least one redundant information item, transmitting said coded information item over a channel after said coding, receiving said coded information item, decoding to obtain, from the received coded information item, an estimation of said useful information item with correction of transmission errors based on said at least one redundant information item, said coding comprises a plurality of elementary coding steps which operate in parallel or in series and are associated with at least one interleaving step, said decoding is iterative and comprises, for each iteration, a plurality of elementary decoding steps associated with interleaving and deinterleaving steps, corresponding to said plurality of elementary coding steps associated with said at least one interleaving step, each of said elementary decoding steps receives a set of information to be decoded and generates a respective set of weighted output information items, determining a threshold quantity characteristic of said decoding as a function of one or more configuration parameters using an adaptive algorithm, generating a characteristic quantity from each set of said weighted output information items generated by each of said elementary decoding steps during each iteration that is characteristic of said set of weighted output information items, comparing said characteristic quantity with said threshold quantity, and interrupting said decoding when said characteristic quantity reaches said threshold quantity.
