Abstract:
A method for reliably receiving digital information from a transmitting device, which information to be receivedappears in discrete subunits so that a predetermined number of subunits correspond to a superunit and appears in encoded form with a certain error detection code, corresponding to a certain error detection decoding method, and additionally with a certain error correction code, corresponding to a certain error correction decoding method; the method comprising the steps oferror correction decoding a superunit, during the error correction decoding, separately estimating the decoding reliability of each subunit of the superunit to be decoded, error detection decoding the error correction decoded superunit, during the error detection decoding, detecting whether or not there were errors in the superunit to be decoded, and if there were detected errors in the decoded superunit, arranging for partial corrective action on the decoded superunit on the basis of the estimated reliabilities of the subunits.
