Patent

CA 2323004

The invention concerns a method which consists in estimating the discrete symbols (d?k¿¿p?) of transmitted signals forming part of the components of a vector D of size N, from a vector Y of a received signal L digital samples, capable of being broken down into Y=AD+Y¿N?, where A is a matrix of size LxN previously determined from measurements of at least one transmission channel reply and Y¿N? represents a vector of L noise samples. To achieve this, the method consists in determining a greater triangular matrix T of size NxN and a vector Z of size N such that the quadratic criteria ?TX-Z??2¿ and ?AX-Y??2¿ are minimal for the same vector X of size N, and dividing the vector Z and the matrix T into blocks so as to operate a minimization of the quadratic criterion block by block travelling along the diagonal of matrix T.

On estime les symboles discrets (dkp) de signaux transmis faisant partie des composantes d'un vecteur D de taille N, à partir d'un vecteur Y de L échantillons numériques d'un signal reçu, pouvant être décomposé en Y=AD+YN, où A est une matrice de taille LxN préalablement déterminée à partir de mesures de la réponse d'au moins un canal de transmission et YN représente un vecteur de L échantillons de bruit. Pour cela, on détermine une matrice triangulaire supérieure T de taille NxN et un vecteur Z de taille N tels que les critères quadratiques TX-Z2 et AX-Y2 soient minimaux pour le même vecteur X de taille N, et on divise le vecteur Z et la matrice T en blocs afin de procéder à une minimisation du critère quadratique bloc après bloc en remontant le long de la diagonale de la matrice T.
