Abstract
(EN)
A wireless transceiver capable of selectively receiving and transmitting as a direct sequence spread spectrum system or as a frequency hopping spread spectrum system is disclosed. The system is particularly suitable for use in a cordless telephone system. The transceiver includes components for both direct sequence spread spectrum transmission and reception and for frequency hopping spread spectrum transmission and reception.
(FR)
La présente invention concerne un émetteur-récepteur radio avec réception et transmission sélectives, fonctionnant comme un système avec étalement du spectre à séquence directe, ou comme un système avec étalement du spectre à sauts de fréquence. Ce système peut particulièrement être utilisé dans une installation de téléphone sans fil. L'émetteur-récepteur comprend de composants à la fois pour la transmission et la réception avec étalement du spectre à séquence directe, et pour la transmission et la réception avec étalement du spectre à sauts de fréquence.
