Fuzzy Comprehensive Evaluation based NLOS Identification for UWB Indoor Positioning [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesUltra-wideband (UWB) positioning technology stands out from many indoor positioning technologies with its advantages of high precision. However, non-line-of-sight (NLOS) propagate leads to heavy range error and reduces position accuracy, this paper ...

CRLBs for WSNs localization in NLOS environment
EURASIP Journal on Wireless Communications and Networking, 2011 Determination of Cramer-Rao lower bound (CRLB) as an optimality criterion for the problem of localization in wireless sensor networks (WSNs) is a very important issue. Currently, CRLBs have been derived for line-of-sight (LOS) situation in WSNs. However,

NLOS Signal Detection Based on Single Orthogonal Dual-Polarized GNSS Antenna
International Journal of Antennas and Propagation, 2017 Nowadays users have a high demand for the accuracy of position and velocity, but errors caused by non-line-of-sight (NLOS) signals cannot be removed effectively. Since the GNSS signal is right-hand circular polarized (RHCP), the axial ratio of the strong

Automated NLO calculations for asymmetric hadron-hadron collisions in MadGraph5_aMC@NLO
The European Physical Journal AWe have extended {\tt MadGraph5\_aMC@NLO} capabilities by implementing computations for asymmetric hadron-hadron collisions, including proton-nucleus, pion-hadron or nucleus-nucleus collisions in order to obtain a tool for automated perturbative computations of cross sections (or ratios of cross sections) in asymmetric reactions at next-to-leading (NLO)
