Abstract
Interference constitutes the bottleneck of Ultra-Wideband (UWB) communications that has been regulated to overlay co-existing narrowband communication systems. To quantify interference and compare UWB systems on that basis, this paper develops a unifying transmission and Rake reception model for UWB multiple access encompassing existing and novel spreading codes. Multi-band UWB systems using single- or multi-carrier modulation are also introduced. Performance analysis (in closed-form) and simulations assess the relative merits of several UWB systems in narrowband interference (NBI), multipath and additive white Gaussian noise (AWGN) effects, for both matched-filter (MF), and minimum mean-square error (MMSE) Rake receivers.
