Performance evaluation of time reversal in intra-vehicular environment

In this paper a time reversal (TR) system combined with multiple-input single output (MISO) antennas over ultra-wideband (UWB) channels are experimentally investigated. An analysis on the spatial and temporal properties of the MISO-TR is presented in the special case of an in-car environment. As the TR can benefit from rich scattering environment, the application of the TR in the in-car environment can achieve very high performances. For some medical reasons, it is not only the peak signal that it is supposed to be focused but also the total energy over the bandwidth, an analysis about the total energy of the equivalent channel impulse responses is presented.
