Title (EN) TRANSMITTING/RECEIVING METHOD FOR MULTI-USER MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM
(FR) PROCÉDÉ D'ÉMISSION/DE RÉCEPTION POUR SYSTÈME MULTI-UTILISATEUR D'ENTRÉE MULTIPLE SORTIE MULTIPLE
Abstract: front page image
(EN)Disclosed is a transmitting/receiving method in a multi-user multiple-input multiple-output (MU-MIMO) channel. The transmitting method includes: performing QR decomposition on a Hermitian transpose matrix of a channel matrix to obtain a first matrix and a second matrix as a triangular matrix; obtaining a preprocessing matrix by using the first matrix; and forming an effective channel based on the preprocessing matrix by a block triangulation technique.
(FR)L'invention concerne un procédé d'émission/de réception dans un canal multi-utilisateur d'entrée multiple sortie multiple (MU-MIMO). Le procédé d'émission consiste notamment : à éxécuter une décomposition QR sur une matrice transposée hermitienne d'une matrice de canal pour obtenir une première matrice et une seconde matrice comme matrice triangulaire; à obtenir une matrice de prétraitement au moyen de la première matrice; et à former un canal efficace sur la base de la matrice de prétraitement par une technique de triangulation de bloc.
