Definitions

  • the invention is subject to methods and systems of communication and may be used to transmit signals. YOU ARE ALREADY Known for modulation for the transmission of information signals in the long wavelength, which is also turned on, which means that the signal is inhibited

Abstract

L'invention concerne des procédés et des systèmes de modulation et peut s'utiliser pour la transmission et la réception de signaux de données. Elle vise la transformation directe de signaux numériques ou d'unités de données par la formation précise d'un signal analogique à partir d'échantillons ou de prototypes connus d'avance. Dans cette invention, on établit une correspondance entre l'échantillon d'un signal analogique possédant une durée prédéterminée aux bits d'un code numérique parallèle, aux positions d'un code numérique sériel ou à une unité d'information de contenus. Chaque échantillon du signal analogique est sélectionné sur la base de sa caractéristique spectrale. On fusionne ensuite en série les échantillons de signaux analogiques qui correspondent au contenu informationnel du message.
