FCM-SSGP Method for Ultra-Wideband Indoor Localization [PDF]

open access: yesJisuanji gongcheng, 2023
Obstacles such as indoor walls, glass, and wooden doors influence the propagation environment of Ultra-Wideband(UWB) signals in UWB indoor positioning, and the environment becomes a Non-Line-of-Sight(NLOS) environment, in which positioning considerably ...

Improvement of strength and water absorption of Interlocking Compressed Earth Bricks (ICEB) with addition of Ureolytic Bacteria (UB) [PDF]

open access: yes, 2018
Interlocking Compressed Earth Brick (ICEB) are cement stabilized soil bricks that allow for dry stacked construction. This characteristic resulted to faster the process of building walls and requires less skilled labour as the bricks are laid dry and ...

NLO predictions for effective field theory with MadGraph5 aMC@NLO [PDF]

open access: yesProceedings of 12th International Symposium on Radiative Corrections (Radcor 2015) and LoopFest XIV (Radiative Corrections for the LHC and Future Colliders) — PoS(RADCOR2015), 2016
Next-to-leading order event generation for the Standard Model effective field theory has started to become available in the MadGraph5_aMC@NLO framework. In this talk we discuss some of the recent progresses in this direction, with a focus on the top-quark sector.

Non-line-of-sight Node Localization based on Semi-Definite Programming in Wireless Sensor Networks

open access: yes, 2009
An unknown-position sensor can be localized if there are three or more anchors making time-of-arrival (TOA) measurements of a signal from it. However, the location errors can be very large due to the fact that some of the measurements are from non-line ...

Cramer-Rao bounds in the estimation of time of arrival in fading channels [PDF]

open access: yes, 2018
This paper computes the Cramer-Rao bounds for the time of arrival estimation in a multipath Rice and Rayleigh fading scenario, conditioned to the previous estimation of a set of propagation channels, since these channel estimates (correlation between ...

Machine learning based GNSS signal classification and weighting scheme design in the built environment: a comparative experiment

open access: yesSatellite Navigation, 2023
None-Line-of-Sight (NLOS) signals denote Global Navigation Satellite System (GNSS) signals received indirectly from satellites and could result in unacceptable positioning errors.

Target Tracking with NLOS Detection and Mitigation in Wireless Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2013
RN and SSR approaches are designed to detect NLOS propagation paths in this paper. When the NLOS propagation paths are detected, an estimation approach for the NLOS range errors is proposed by using residual-error decomposition. The approach can estimate

Stochastic Geometry Modeling and Performance Evaluation of mmWave Cellular Communications

open access: yes, 2015
In this paper, a new mathematical framework to the analysis of millimeter wave cellular networks is introduced. Its peculiarity lies in considering realistic path-loss and blockage models, which are derived from experimental data recently reported in the
