Abstract

L’invention concerne un procédé d’émission d’une séquence de bits à émettre à une fréquence fb. Un ensemble de codes est préalablement déterminé, dans lequel chaque code est associé à une valeur possible d’un bloc de Nb bits, et chaque code comporte un ensemble ordonné de Ns symboles binaires destinés à être émis à une fréquence fs. Le procédé comporte : - un découpage de la séquence de bits en N blocs de Nb bits, la fréquence fs et les nombres N et Nb étant choisis de sorte que Ns x fb = N x Nb x fs, - une association d’un code à chacun des N blocs en fonction de la valeur desdits blocs, - un entrelacement des symboles binaires des N codes correspondant respectivement aux N blocs de bits à émettre, les symboles binaires entrelacés étant transmis à une fréquence fc telle que N x fs = fc.
