Abstract
The subject of the present invention is a method for correcting transmission errors in a data stream transmitted by a communications system using a protocol stack. According to the invention, the method consists in utilizing the redundancy of sequences whose content is fixed across several layers in a stack of protocols so as to correct transmission errors; the method consisting to this end in searching at the level of the receiver for sequences corresponding to a known sequence present in the stream received and doing so by detecting sequences similar to this known sequence, non-similar sequences not being retained; the method consisting furthermore, when similar sequences are present, in detecting transmission errors in the known sequence and in modifying the similar sequences (erroneous sequences) with the aid of the known sequence.
