Title (EN) TRANSMISSION AND RECEPTION SYSTEM AND METHOD BASED ON CODE DIVISION
(FR) SYSTÈME DE TRANSMISSION ET DE RÉCEPTION ET PROCÉDÉ FONDÉ SUR LA DIVISION DE CODE
Abstract: front page image
(EN)The code division (CDMA) transmission method includes the step of multiplying a signal (a) to be transmitted, represented by a vector, by a matrix (S), whose result is represented by a vector (x), said method being characterized in that: • taking a basic sequence with substantially-ideal periodic autocorrelation; • constructing said matrix (S) by a cyclical translation of said basic sequence, in such a way that the columns of said matrix (S) are the cyclical shifts of the basic sequence; • adding a cyclic prefix to said resulting vector (x).
(FR)L’invention concerne un procédé de transmission par division de code (CDMA) comprenant la phase de multiplication d’un signal (a) à transmettre, représenté par un vecteur, par une matrice (S), dont le résultat est représenté par un vecteur (x), ledit procédé étant caractérisé par les étapes suivantes : • prise d’une séquence de base avec une autocorrélation périodique sensiblement idéale ; • construction de ladite matrice (S) par translation cyclique de ladite séquence de base, pour que les colonnes de ladite matrice (S) correspondent aux décalages cycliques de la séquence de base ; • addition d‘un préfixe cyclique audit vecteur résultant (x).
