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...
On-body communications around the human torso are considered, using ultra-wideband transmissions. The velocity of the diffracted wave propagating around the body is extracted from frequency- domain spatial correlation analyses.
In this paper, spatial correlations are studied for the development of a UWB multi-sensors MIMO Body Area Network system, where the sensors communicate with a multi-antenna central device. The correlation in the frequency and delay domains has been extracted from channel measurements on the human body.
