Title (EN) PARALLELIZATION OF A TOMLINSON-HARASHIMA-PRECODER FOR MIMO TRANSMISSION IN A DSL SYSTEM
(FR) PARALLÉLISATION D'UN PRÉCODEUR DE TOMLINSON-HARASHIMA POUR TRANSMISSION MIMO DANS UN SYSTÈME DSL
Abstract:
(EN) A Digital Subscriber Line Access Multiplexer, DSLAM, structure (1) comprising at least two encoders, ECs (2), and a linear precoder, LP (3). The ECs encode signals into encoded signals. At least one of the ECs is an independent Tomlinson-Harashima-Precoding, THP, structure comprising a feedback matrix processor (6) and a modulo operator (7). The LP (3) comprises an encoding matrix and processes the encoded signals into transmission signals for transmission through a multiple-input-multiple-output, MIMO, channel (4).
(FR) Un multiplexeur d'accès de ligne d'abonné numérique, DSLAM, une structure (1) comprenant au moins deux codeurs, EC (2), et un précodeur linéaire, LP (3). Les EC codent des signaux en signaux codés. Au moins un des EC est une structure indépendante du précodeur Tomlinson-Harashima, THP, comprenant un processeur de matrice de rétroaction (6) et un opérateur modulo (7). Le LP (3) comprend une matrice de codage et traite les signaux codés en signaux de transmission pour une transmission par l'intermédiaire d'un canal MIMO (4) à entrées multiples et sorties multiples.
