Techniques multi-antennes émission-réception ; Applications aux réseaux domestiques sans fil

Abstract : Until recently restricted to office applications, wireless local area networks (WLAN), propelled by advances in electronics and signal processing, is ermerging as the most promising technology to bring connectivity in home environment. Obviously more exible
and less expensive than their wired counterparts, the future of WLAN is hindered by the capacity of keeing the pace with the exponential growth in data rate sustained by multimedia communications. A major breakthrough came recently with the multiple-Input Multiple-Output (MIMO) communication architecture that uses multiple-antenna arrays at both transmitter and receiver ends. This concept generalizes all previously known transmission systems and allows a far more sophisticated processing of space to
yield unprecedented spectral efficiencies.

Few existing WLAN standards can cope with high data rate multimedia services. The HIPERLAN2 specification, achieving data rates up to 54 Mbps in the 5 GHz spectrum, is among them and the question naturally arises as to determine the potential of a MIMO-based physical interface. This thesis, led in the framework of a CIFRE grant between THOMSON multimedia and the IETR (Rennes Institute for Electronics and Telecommunications), provides some clue to this problem.
