Title (EN) FREQUENCY HOPPING COMMUNICATION SYSTEM
(FR) SYSTEME DE COMMUNICATION A SAUTS DE FREQUENCE
Abstract:
(EN) A spread spectrum radio frequency communication system comprising a plurality of transmitters adapted to operate at different carrier frequencies having a preassigned frequency separation, such carrier frequencies randomly changing in accordance with a common pseudo-random code. Each of the transmitters has a predetermined bandwidth and the carrier frequencies of the transmitters are in accordance with the bandwidth of the transmitters.
(FR) Système de communication à radiofréquence à large spectre comprenant une pluralité d'émetteurs adaptés pour fonctionner à des fréquences porteuses différentes ayant une séparation de fréquence préattribuée, lesdites fréquences porteuses changeant de manière aléatoire selon un code commun pseudo-aléatoire. Chacun des émetteurs possède une largeur de bande prédéterminée et les fréquences porteuses des émetteurs correspondent à la largeur de bande desdits émetteurs.
