ULTRA-WIDEBAND SPATIAL CORRELATION STUDY FOR MULTI- SENSOR MULTI-ANTENNA BODY AREA NETWORKS

This paper is a first step towards the development of UWB multi-sensors MIMO body area networks, where the sensors communicate with a multi-antenna central device. The spatial correlation in the frequency and delay domains has been extracted from channel measurements on the human torso. We highlight two behaviours depending on the propagation mechanisms: diffraction around the body and environment reflections.
