Abstract
In this paper, the performances of a time reversal (TR) system inside an intra-vehicular environment are experimentally investigated. Analysis of the spatial and temporal properties of Multiple-Input-Single-Output (MISO) TR systems over ultra-wideband channels are presented. In order to study the performances of the MISO-TR within an occupied car, measurements were made by varying the number of passengers and by studying different configurations of antennas. Results indicate that the TR technique works fine in this special environment even with the presence of the passengers. As TR can achieve good robustness against changes in the channel, an analysis about the robustness in the case of any change in the number of passengers is presented.
