Abstract
L'invention concerne un dispositif et un procédé destinés à réduire le rapport puissance de crête/puissance moyenne de la puissance d'émission d'une station mobile dans un système de communication mobile, lequel procédé consiste à étaler et à moduler les données d'émission au moyen d'une séquence d'étalement complexe. Cette séquence d'étalement complexe est générée de manière à présenter une pluralité de microblocs et une différence de phase de 90· entre deux microblocs complexes successifs en réponse à chaque microbloc d'une séquence de pseudo-bruit. Ce dispositif et ce procédé permettent de commander de façon souple la puissance d'émission de la station mobile par limitation du rapport puissance de crête/puissance moyenne à une plage déterminée, et donc par confinement de la puissance d'émission de la station mobile à une partie caractéristique linéaire de la courbe caractéristique d'un amplificateur de puissance. On empêche ainsi la phase de la séquence d'étalement complexe de tourner de 180· (soit .pi.) pour maintenir la puissance d'émission de la station mobile dans la partie linéaire de la courbe caractéristique de l'amplificateur de puissance.
