Exploiting LTE Signals for Navigation: Theory to Implementation
TL;DR: A threshold-based approach for detecting the first peak of the channel impulse response is proposed in which the threshold adapts to the environmental noise level and is demonstrated to be robust against noise and interference in the environment.
Proceedings ArticleDOI
Indoor localization using FM radio signals: A fingerprinting approach
TL;DR: A new positioning system is proposed based on broadcast FM as a signal of opportunity, with significant benefits for indoor positioning, that uses FM signal strength fingerprinting.

Signals of opportunity aided inertial navigation
Zak M. Kassas,Joshua J. Morales +1 more
TL;DR: The SOP-aided INS produces bounded estimation errors in the absence of GNSS signals, and the bounds are dependent on the quantity and quality of exploited SOPs.

Indoor Location Fingerprinting Using FM Radio Signals
TL;DR: A new positioning system is proposed based on frequency modulation (FM) broadcast as a signal of opportunity, with significant benefits for indoor positioning, which uses FM signal strength fingerprinting.

Cognitive radio: brain-empowered wireless communications
TL;DR: Following the discussion of interference temperature as a new metric for the quantification and management of interference, the paper addresses three fundamental cognitive tasks: radio-scene analysis, channel-state estimation and predictive modeling, and the emergent behavior of cognitive radio.
Fusion of Low-Cost Imaging and Inertial Sensors for Navigation
Michael J. Veth,John F. Raquet +1 more
TL;DR: An image-aided inertial navigation algorithm is implemented using a multi-dimensional stochastic feature tracker and specifically evaluated for operation using lowcost, CMOS imagers and MEMS inertial sensors.
Indoor Industrial Machine Guidance Using Locata: A Pilot Study at BlueScope Steel
Joel Barnes,Chris Rizos,Mustafa Kanli,David Small,Gavin Voigt,Nunzio Gambale,Jimmy Lamance,Terry Nunan,Chris Reid +8 more
TL;DR: The feasibility of Locata for industrial machine guidance is demonstrated through a trial at the BlueScope steelworks through the use of the technology to track a crane within the slab handling yard.
