Definitions

  • the clouds 40 in Figure 2 each have the form of a square, with points on each corner of the square, the respective edges of the square being parallel to and perpendicular to, respectively, arrow 41. Rotating the small square over 45° is feasible as well.
  • Another solution is based on a ring-type constellation among the various signal points. From general transmission praxis it is known that time- and space-multiplexing and -interleaving can for a good deal be interchanged.

Abstract

L'invention concerne un système de transmission équipé d'un émetteur/récepteur pour la transmission de données sur une voie de transmission à qualité non uniforme dans le temps et/ou dans l'espace par rapport au récepteur. Dabord, l'émetteur répartit les données en blocs de données successives de taille uniforme, et les données de chaque bloc en groupes de taille uniforme. Ensuite, l'émetteur assure le codage des données de tous les groupes au moyen d'un code détecteur d'erreurs en utilisant un code distinct pour chaque groupe. De plus, l'émetteur répartit les données codées des différents groupes en paquets de données ayant une taille uniforme et, à l'intérieur d'un bloc, il attribue de manière uniforme et cyclique les paquets des groupes respectifs à une série de sous-voies entrelacées dans le temps/ou dans l'espace et multiplexées. Enfin, le système est en mesure de contrôler les différents niveaux de puissance de transmission correspondant aux groupes respectifs de tel ou tel bloc.
