Systèmes de communication MIMO non-linéaires : estimation de canal et récupération d'information en utilisant des modèles de Volterra

Autor: Rolim Fernandes, Carlos Alexandre

Du à la présence de dispositifs non-linéaires comme des amplificateurs de puissance (PAs) et des instruments optiques, les signaux de communication sont parfois corrompus par des distorsions non-linéaires. Dans ce cas, des modèles non-linéaires

International audience; A three-hop AF MIMO relay system with tensor coding at the source and the relays is considered in this paper. The signals received at destination form a fifth-order tensor that satisfies a high-order nested Tucker decompositio

International audience; The aim of this paper is twofold. In a first part, we present a new tensor decomposition that we call Tucker train decomposition or nested Tucker decomposition (NTD). NTD can be viewed as a particular case of tensor-train deco
