Abstract

a. Procédé et installation de transmission d'un code. b. Procédé de transmission de code caractérisé en ce qu'on ajoute un premier bit redondant à un signal de bit d'information, ce bit redondant n'étant pas divisible par un polynôme général même si tous les bits du signal de bit d'information sont de niveau << 0 >> ou << 1 >>; on divise le résultat de cette addition du premier bit redondant et du signal de bit d'information par le polynôme général pour obtenir un second bit redondant comme résidu de la division, on ajoute ce second bit redondant au signal de bit d'information pour donner un code résultant, on transmet ce code résultant, on ajoute le premier bit redondant au code résultant, transmis, à la réception et on divise le code résultant, reçu par le polynôme général pour détecter l'erreur par l'existence d'un résidu à cette dernière division.
