Abstract:
(EN) A binary encoder comprising: an input adapted to receive a binary signal, an encoding processor adapted to: compute a plurality of different variations of the binary signal, combine each one of the plurality of different variations with a different redundancy sequence to create a plurality of optional output binary sequences, and select one of the plurality of binary sequences according to a binary digit prevalence, and an output adapted to output the selected binary sequence. Corresponding decoder adapted to identify a redundancy sequence of a received binary signal, to select a transformation function according to said redundancy sequence and to convert the binary signal according to the selected transformation function.
(FR) L'invention concerne un encodeur binaire comprenant : une entrée conçue pour recevoir un signal binaire, un processeur d'encodage conçu pour : calculer une pluralité de variations différentes du signal binaire, combiner chaque variation de la pluralité de différentes variations avec une séquence de redondance différente pour créer une pluralité de séquences binaires de sortie facultatives, et sélectionner une séquence parmi la pluralité de séquences binaires selon une prévalence de chiffre binaire, et une sortie conçue pour fournir la séquence binaire sélectionnée. Un décodeur correspondant est conçu pour identifier une séquence de redondance d'un signal binaire reçu, sélectionner une fonction de transformation en fonction de ladite séquence de redondance et pour convertir le signal binaire en fonction de la fonction de transformation sélectionnée.
