Abstract

An ultra-wideband (UWB) system has a frequency bandwidth that overlaps with spectra of many existing narrowband radio systems. As a result, impact of narrowband interference (NBI) becomes a key issue in the development of UWB systems. In this paper, under the IEEE802.15.4a industrial line-of-sight (LOS) channel model, the effects of NBI on the performance of the recently proposed differential code-shifted reference (DCSR) UWB systems is assessed analytically and through computer simulations. The results shows that DCSR is inherently robustness to NBI and the values of code length N_f, as well as transmission code number M play an important role in mitigating NBI. Therefore, shifting and detection codes need to be carefully designed and selected.
