[Emulation de canaux MIMO grâce à des chambres réverbérantes couplées]
Cette contribution décrit un nouveau moyen d'émuler expérimentalement des canaux MIMO grâce à deux chambres réverbérantes à brassage de modes (CRBM), couplées entre elles par un guide d'onde. Ce guide permet de contrôler le degré de diversité du canal, les chambres générant des environnements de Rayleigh. Ce dispositif devrait permettre de tester expérimentalement les systèmes de communication MIMO dans des environnements parfaitement définis et donc reproductibles. Après avoir rappelé rapidement les potentialités et les limitations inhérentes à l'utilisation d'une chambre unique, nous décrirons l'approche théorique et les résultats expérimentaux qui ont été obtenus lors de l'analyse de deux chambres couplées.
This article describes a new experimental set up for emulating MIMO channels, based on two mode stirred reverberation chambers (MSRC), coupled together with a waveguide. This guide allows one to control the order of the channel diversity, the chambers generating a Rayleigh environment. This set up could thus be used to perform tests of MIMO communication systems in perfectly defined environments and thus under reproducible conditions. After a brief recall of the advantages and drawbacks of using a single reverberation chamber, we describe the theoretical approach and the experimental results for the analysis of two coupled chambers.
