Abstract

L'invention concerne un procédé de détermination d'au moins une séquence d'étalement associée à un utilisateur, destinée à être utilisée dans un système de transmission mettant en œuvre K utilisateurs et M ressources, selon lequel, un symbole de données associé à l'utilisateur k, k E [1 étant destiné à être étalé sur un bloc de N ressources avec K & gt; N & gt; 1, et M = aN, et un vecteur de superposition de données sur le bloc de N ressources s'exprimant sous la forme y = Sx, avec S une matrice d'étalement dans laquelle les éléments composant chaque colonne forment la séquence d'étalement sk, sur le bloc de N ressources, associée à l'utilisateur k, ledit procédé met en œuvre la détermination (31) des valeurs des éléments non nuls de ladite matrice d'étalement de taille NxK, en minimisant un premier critère de corrélation entre les différents vecteurs de superposition de données.The invention relates to a method for determining at least one spreading sequence associated with a user, intended to be used in a transmission system implementing K users and M resources, according to which, a data symbol associated with the user k, k E [1 being intended to be spread over a block of N resources with K > N > 1, and M = aN, and a vector of superposition of data on the block of N resources expressed in the form y = Sx, with S a spreading matrix in which the elements composing each column form the spreading sequence sk, on the block of N resources, associated with the user k, said method implements the determination (31) of the values of the non-zero elements of said spreading matrix of size NxK, by minimizing a first correlation criterion between the different data overlay vectors.
