Abstract :
In this paper, the effects of multipath interferences on the performance of a multiuser ultra-wideband (UWB) fast acquisition system operating in an underground indoor fading channel are evaluated and compared. Various pulse shapes are considered with different scenarios of interference and Gaussian noise in extensive Monte-Carlo simulations. The results show the 6 order Gaussian derivative as the most suitable pulse shape for this new UWB fast acquisition system suggested for ranging in a peculiar confined environment, offering very acceptable positioning error range at high levels of noise and interference, while also yielding greatly reduced complexity and acquisition time.
