Optimum multi-user detection in ultra-wideband (UWB) multiple-access communication systems

This paper investigates multi-user detection in multiple-access communication systems based on ultrawideband (UWB) technology. As user numbers increase and the bandwidth to pulse repetition frequency (PRF) decreases, multiple-access interference (MAI) is expected to adversely affect system capacity and performance. The paper presents a framework for the design of multi-user detectors and proposes the optimum multi-user detector for UWB. Numerical examples illustrate the performance of the optimum detector versus that of the conventional single-user UWB detector.
