Abstract

Un procédé de transmission de données numériques, approprié à la transmission acoustique de données numériques, consiste à coder les données sous la forme de mots binaires grâce à l'utilisation d'un code redondant permettant d'obtenir une séquence de symboles de modulation et à transmettre les symboles dans plusieurs canaux auxiliaires à des fréquences différentes. Les symboles sont entrelacés dans le temps avec une répartition telle que deux symboles adjacents ne peuvent pas être transmis à la suite dans le temps et à la même fréquence. Un décodeur de type Virtibi est de préférence utilisé. Des constructions particulières d'un émetteur et d'un récepteur sont également décrites.
