Abstract
Them has been an emerging interest in non-coherent ultrawideband (UWB) communications, mainly, due to their low-complexity and low-power consumption. Duo to the large transmission bandwidth, UWB systems; need to,exist and contend with many narrowband communication systems. As a result, the presence of narrowband interference (NBI) severely degrades the system performance. In this paper, we consider transmitted reference signaling and analyze its bit error probability in a multipath fading channel when NBI is present. In particular, we consider the case of multiple NBI. whom the interfering nodes tore scattered according to a spatial Poisson process. Our framework is simple enough to allow a tractable analysis and provide valuable insights to the design of practical UWB systems.
