Performance Analysis of Ultra-Wide Band Intravehicle Propagation in Multi-user Environments
Ultra Wideband (UWB) technology attracts attention from automotive manufacturers as a potential way to construct an intra-vehicle wireless sensor network, which is also called Networked Control System (NCS). Given that large numbers of sensor transceivers are placed inside a vehicle, the NCS operates in a multi-user interference (MUI) limited environment. This paper evaluates the effect of MUI on the performance of UWB Intra-vehicle NCS, adopting the Standard Gaussian Approximation (SGA) model for MUI. Through simulations, we compare the multi user system performance of intra-vehicle communications with that of indoor/outdoor environments. Then we further make a comparison between the two different intravehicle NCS under different density of sensor transceivers. Under the SGA hypothesis, we also prove that, in an UWB intra-vehicle environment, the SGA provides weak estimations of BER when low values of the user bit rate or sparse sensor transceivers are considered. Our simulations depend on the recently proposed channel model for intra-vehicle environment which is based on the standard IEEE 802.15.3a.
