Abstract

L'invention concerne un système à sauts de fréquence, dans lequel la largeur de bande de saut de fréquence est modifiée en réponse à une modification de conditions de canal ou de commande. On peut également modifier la puissance de sortie en même temps que la bande de fonctionnement, de sorte que ledit système satisfait à tout moment aux exigences de régularité du pays dans lequel il fonctionne.
