In this paper, analytical methods for calculating the average probability of bit error of direct sequence ultra wideband (DS-UWB) system and time hopping pulse position modulation (TH-PPM) UWB system are given. In our proposed multiuser DS UWB system, the bipolar pulse amplitude modulation is used in order to achieve better performance. As we know, more attention is paid to the TH-PPM UWB systems recently. In this paper, we first introduce the accurate BER calculation methods of the multiuser DS-PAM and TH-PPM UWB systems and then give the performance analysis over an ideal AWGN channel and a correlation receiver. Furthermore, we also introduce their applications in image transmission and data transmission and give the simulation results. The analytical method yields simple and exact formulas relating the performance to the system parameters.
