Abstract:
1. A method for correcting transmission errors on reception in a data stream transmitted by a communication system using a stack of multilayer protocols, said method comprising: receiving an incoming data stream including packets of data generated by the stack of multilayer protocols, each of the data packets includes protocol fields whose content is constant for all the data packets; constructing a known sequence without adding information to the transmitted data stream, the known sequence including symbols characteristic of various layers of the stack of multilayer protocols and belonging to the protocol fields of the constant content; searching at a level of a receiver for sequences similar to the known sequence, wherein non-similar sequences are not being retained; in a case where similar sequences are present, detecting erroneous known sequences based at least in part on a measure of similitude between the similar sequences retained and the known sequence constructed; and modifying the erroneous known sequences detected.
