Abstract
La présente invention concerne un modem radioélectrique sans fil qui peut être incorporé à un système hôte ou connecté par l'intermédiaire d'un port PCMCIA ou d'un port d'accès similaire à un système hôte. Ce modem comporte des circuits de modulation/démodulation HF constitués d'éléments électroniques fonctionnant qui réduit au minimum l'interférence HF entre le modem radio et le système hôte. L'économie d'énergie du modem radioélectrique est optimisée 1) par simplification par traitement de modulation du signal à l'aide d'une table de transition d'onde deux-points, ce qui réduit le temps de traitement et 2) par incorporation d'une fonction "mode sommeil" dans laquelle tous les circuits n'ayant pas de fonction d'horloge sont déconnectés lorsqu'ils ne sont pas utilisés.
