Abstract

Ultra Wideband (UWB) communication system utilizing impulse signals is interested recently. In the impulse radio based UWB system (IR-UWB), lots of different shaped pulses have been considered to evaluate and improve the accuracy in positioning technique. The choice of the pulse shape and pulse width strongly affects the choice of receiver bandwidth, the performance and positioning accuracy of system. In this paper, we propose an analytical method to select the pulse parameters that match the positioning distance to improve the accuracy of the system. Computer simulation results show that the proposed system gives higher accuracy than conventional narrow band (NB) system with the average error of the proposed system is 0.05 m while in the NB system is 0.35 m.
