Abstract :
In this paper we study the effect of bandwidth on performance of positioning systems. We introduce a benchmark for performance evaluation, distance measurement error (DME). We analyze DME and introduce a model for it. We show that there are two causes for DME, multipath dispersion and undetected direct path (UDP), and we study the effect of bandwidth on each of these components in DME. We show that increasing the bandwidth can decrease the multipath DME, but for the UDP effect, beyond a certain point it increases the DME. Thus there is an optimum bandwidth for minimizing overall error. The results were obtained using a database of UWB measurements conducted in an indoor propagation environment
