Abstract

2095257 9305589 PCTABS00161 Avant de moduler la porteuse de transmission, chaque signal de données binaire se trouve codé individuellement en un symbole distinct appartenant à une constellation PSK de N symboles associés à N points distincts de manière à produire deux trains de signaux binaires (I, Q), le première train de signaux binaires (I) étant en phase avec le signal entrant et le second train de signaux binaires (Q) étant en quadrature de phase avec le signal entrant, et en ce que chacun des deux trains de signaux binaires (I, Q) précités est affecté d'une signature propre par combinaison avec un code d'étalement distinct (CI, CQ), de manière à produire deux trains de signaux composites étalés destinés à être appliqués chacun à un modulateur, les deux codes d'étalement (CI, CQ) précités étant en corrélation croisée quasi-orthogonale. Le procédé est utilisable dans un système de communications par satellite en particulier pour la transmission numérique du son et les communications par micro-terminaux terrestres.
