Abstract
Système comprenant un émetteur et un récepteur pour la transmission de signaux de donnée binaires à une frequence symbole donnée, l'étage de modulation de l'émetteur produisant un signal d'onde porteuse à modulation angulaire ayant une amplitude pratiquement constante et une phase continue et le signal modulé transmis étant démodulé dans le récepteur de façon orthogonale et cohérente. L'étage de modulation est agencé de façon que la phase du signal modulé, au cours de chaque intervalle symbole, varie d'une quantité comprise dans la série - pi /2, - pi /4, 0, pi /4, pi /2 (radian), cette quantité, pour l'intervalle symbole considéré, étant déterminée par au moins deux symboles de données successifs, la forme de la phase à l'intérieur de cet intervalle symbole étant déterminée par une version filtrée d'au moins ces deux symboles de données successifs. Application : transmission de données par liaisons radioélectriques.
