“ Ultra - Wideband Ranging in Dense Multipath Environments
Ultra-wideband (UWB) radio, a new carrierless communication scheme using impulses, is a candidate technology for future communication and ranging applications. Recent progress on both in the technical and regulatory side of this technology has made this possible. The fine time resolution and material penetration capability of UWB signals has created a vision of novel ranging and positioning app...
متن کاملConcurrent Ranging in Ultra-wideband Radios: Experimental Evidence, Challenges, and Opportunities
This paper investigates the feasibility of a novel primitive for concurrent ranging in ultra-wideband (UWB) radios. Conventional ranging protocols schedule the packet transmissions used to estimate distance to be separate in time. In contrast, our concurrent ranging primitive relies on the overlapping of these transmissions; when a ranging request is issued by an initiator node, all nodes in ra...
متن کاملA Comprehensive Evaluation of Indoor Ranging Using Ultra-Wideband Technology
Ultra-wideband technology shows promise for precision ranging due to its fine time resolution to resolve multipath fading and the presence of lower frequencies in the baseband to penetrate walls. While a concerted effort has been conducted in the extensive modeling of the indoor UWB channel in recent years, to our knowledge only two papers have reported ranging performance, but for limited rang...
متن کاملRobust Target-relative Localization with Ultra-Wideband Ranging and Communication
In this paper we propose a method to achieve relative positioning and tracking of a target by a quadcopter using Ultra-wideband (UWB) ranging sensors, which are strategically installed to help retrieve both relative position and bearing between the quadcopter and target. To achieve robust localization for autonomous flight even with uncertainty in the speed of the target, two main features are ...
متن کاملA Framework for NLOS Ultra-Wideband Ranging in Collaborative Mobile Robot Systems
Ultra-wideband (UWB) localization is one of the most promising indoor localization methods. Yet, non-line-ofsight (NLOS) positioning scenarios remain a challenge and can potentially cause significant localization errors. In this work, we leverage the collaborative paradigm of a multi-robot system by sharing relative positioning information, and thus alleviating error susceptibility in NLOS rang...
