Ultra wideband (UWB) wireless communications systems are currently being considered for several applications requiring ultra high speed wireless data access. UWB signals employ very short duration pulses to transmit information over an indoor frequency selective environment. Most of the previous research related to multi-access time hopping UWB employed the conventional single user matched filter receiver. In this paper, we propose a UWB multiuser detection technique to improve the UWB communication system performance. To take advantage of the dense multipath channel and achieve high speed short range communications, we propose a multiuser receiver which employs a partial Rake receiver followed by a successive interference cancellation technique with optimal ordering. Numerical results demonstrate that significant performance improvements would result when the proposed architecture is employed.
