Abstract

Abstract Translated from French Procédé pour le codage et le décodage d'une émission à large bande, dite à étalement de spectre, dans lequel le signal à transmettre est modulé par un code formé d'une séquence pseudo-aléatoire de période T composée de deux demi-séquences de période T/2, le code utilisé pour la démodulation, à la réception, étant composé des mêmes demi-séquences l'une d'elles étant affectée d'une rotation circulaire par rapport à l'autre. Method for coding and decoding a broadband transmission, called spread spectrum, in which the signal to be transmitted is modulated by a code formed by a pseudo-random sequence of period T composed of two half-sequences of period T / 2, the code used for demodulation, on reception, being composed of the same half-sequences one of them being assigned a circular rotation with respect to the other.
