Conception et réalisation de la partie numérique d'un simulateur matériel pour les canaux de propagation MIMO

Abstract : The need to improve the capacity of wireless networks, for the data transmission and multimedia applications of the digital communication systems, has to focus on MIMO communication techniques to increase the data rate and the quality of services. MIMO systems use antenna arrays at both the transmit and the receive sides of a radio link and exploit the spatial dimension for the transmission. The performance of a communication system can be evaluated using a hardware simulator of radio propagation channels. This Ph.D. deals with the design and the implementation of the digital block of a hardware simulator of MIMO propagation channels, for both UMTS and WLAN networks. The hardware simulation of radio channel provides the necessary processing speed. Other advantages of the hardware simulation are the real time performance evaluation and the comparison of different systems in a time varying radio propagation channel under the same test conditions. Two approaches have been considered, one for indoor environments, the other for outdoor environments. The proposed digital architectures were studied and implemented within FPGA. Performance and complexity evaluation shows the interest of these architectures. This work was carried out under the project SIMPAA 2, with the support of the "Région Bretagne".
