Journal ArticleDOI
Ranging With Ultrawide Bandwidth Signals in Multipath Environments
TL;DR: In this paper, the authors provide an overview of ranging techniques together with the primary sources of TOA error (including propagation effects, clock drift, and interference) and describe fundamental TOA bounds (such as the Cramer-Rao bound and tighter Ziv-Zakai bound) in both ideal and multipath environments.
Journal ArticleDOI
Effects of Noise Power Estimation on Energy Detection for Cognitive Radio Applications
TL;DR: The performance of the ED with estimated noise power (ENP), addressing the threshold design and giving the conditions for the existence of the SNR wall is analyzed, and analytical expressions for the design curves (SNR vs. observation time for a target performance) for the ENP-ED are derived.
Journal ArticleDOI
The effect of narrowband interference on wideband wireless communication systems
TL;DR: Close-form bit-error probability expressions for spread-spectrum systems are derived by approximating narrowband interferers as independent asynchronous tone interferers by developing a new analytical framework based on perturbation theory to analyze the performance of a Rake receiver in Nakagami-m channels.
Journal ArticleDOI
Coexistence Between UWB and Narrow-Band Wireless Communication Systems
Marco Chiani,Andrea Giorgetti +1 more
TL;DR: This paper considers a point-to-point UWB (NB) under the interference generated by a finite number of NB (UWB) radio transmitters, and considers channels including additive white Gaussian noise and multipath fading both for the victim and the interfering links.
Journal ArticleDOI
Localization Capability of Cooperative Anti-Intruder Radar Systems
TL;DR: System aspects of an anti-intruder multistatic radar based on impulse radio ultrawideband (UWB) technology are addressed, and it is highlighted how area coverage and transmitted power, and localization uncertainty, require opposite criteria of nodes placement.
