Caractérisation et modélisation du canal de propagation radio en contexte Ultra Large Bande

Abstract : Ultra Wide Band (UWB) is a high rate, short range radio communication technique using frequency bands in the order of 500 MHz to several GHz. This thesis presents an experimental characterisation of the UWB propagation channel in order to propose models for the development of such systems.
Two proposed sounding techniques enable the measurement of the static channel in the 3.1 – 11.1 GHz band and real time channel sounding in the 4 – 5 GHz band. Several measurement campaigns performed in the indoor office environment are detailed. The analysis of the collected data highlights the large scale parameters and small scale fading of the static channel, with a particular study on the influence of the frequency. Specific studies are dedicated to the UWB channel variations linked to the displacement of the antennas and the motion of people. A statistical model is proposed, reproducing the effects of the UWB propagation channel, in both static and dynamic configurations.
