Recovery of transmission errors

A device for recovering transmission errors comprising:

• an input means for receiving a data packet comprising an error detection code associated to data contained in the packet, wherein the data associated to the error detection code comprises primary data and secondary data,
• an error detection code checking means for checking the error detection code of the received packet to detect an erroneous state of the associated data,
• a primary data correction means operable to determine a finite set of candidate values for the primary data and, for each candidate values of the set, to determine a marginal likelihood of the candidate value over the secondary data as a function of the error detection code of the received packet, to determine a first correlation between the primary data of the received packet and the candidate value, and to select a corrected value for the primary data among the set of candidate values as a function of said marginal likelihoods and said first correlations.
