  • pre-reduction of the data to be transmitted may be followed by another reduction using known compression techniques, such as the Zip compression format or bit-accurate rather than bit-wise encoding.

Abstract

Réduire la taille des paquets lors d'une transmission de données C2X permet d'augmenter la portée de transmission et le nombre de paquets de données transmis par unité de temps. Par exemple, seules des informations partielles sont transmises, lesquelles peuvent être converties en informations complètes par le récepteur au moyen d'informations complémentaires provenant d'une autre source. Des caractéristiques de transmission du support radio, d'une part, et des bases d'informations communes associées au système, d'autre part, peuvent être utilisées pour obtenir les informations complètes.
