Patent

CA 2371996

In a data transmitter (36) having a data encoder, an encoder (26) mode is detected. Thereafter, an excluded codeword output by the encoder operating in the encoder mode is identified. Next, a selected bit in the excluded codeword caused to have a predetermined value to produce a non-excluded codewword. Finally, the excluded codeword is substituted with the non-excluded codeword, wherein the non-excluded codeword is selected to mitigate effects of a decoding error in a receiver (54) associated with the excluded codeword.

Dans un émetteur de données (36) comprenant un codeur de données, un mode codeur (26) est détecté. Ensuite, un mot de code exclu sorti par le codeur fonctionnant dans le mode codeur est identifié. Ensuite, un bit sélectionné dans le mode de code exclu reçoit une valeur prédéterminée afin de produire un mot de code non exclu. Enfin, le mode de code exclu est remplacé par le mot de code non exclu, le mot de code non exclu étant sélectionné pour réduire les effets d'une erreur de décodage dans un récepteur (54) associé au mot de code exclu.
