Performance comparison of the different IR-UWB receivers in wireless body area networks

Abstract

This paper gives a performance overview of different types of ultra wideband (UWB) receivers that can be used in wireless body area network (WBAN) applications. The studied receivers are based on both coherent and non-coherent detections. The signal structure is following the IEEE 802.15.4a standard and the channel models used in the simulations are based on the experimental studies carried out at a real hospital environment. Two different links are used; on-body link and a link from body to external access point. Otherwise, the transceiver chain is kept the same all the time to distinguish the differences between studied cases, thus different channels.
