%X Ultra-wideband impulse radio is a developing high speed wireless access technology. In this paper, the principle of ultra-wideband multiaccess communication is analyzed with the transmitting signal. In order to study the system performance in mulitpath channels, the deterministic two-path model and the statistical S-V model are employed for evaluating the bit error rates of the system by simulation. The results indicate that the intersymbol interference and multiple access interference are the main factors that degrade the system performance, which, on the other hand, may be improved by antenna diversity.
