Published in 2020 at "GPS Solutions"

DOI: 10.1007/s10291-020-01006-w

Abstract: Urban environments present significant challenges to global navigation satellite system (GNSS) positioning. GNSS signals are often obstructed by buildings and other obstacles, leading to reflection and diffraction, which cause major line-of-sight (LOS) and non-line-of-sight (NLOS)… read more here.

Published in 2023 at "IEEE Wireless Communications Letters"

DOI: 10.1109/lwc.2023.3240846

Abstract: The radio channel modeling and location system are the focus of many research fields. However, their performance is largely limited by line-of-sight (LOS) and non-line-of-sight (NLOS) conditions. Currently, the most popular LOS/NLOS identification algorithm is… read more here.

Published in 2022 at "IEEE Transactions on Communications"

DOI: 10.1109/tcomm.2023.3236381

Abstract: The provision of accurate localization is an increasingly important feature of wireless networks. To this end, a reliable distinction between line-of-sight (LOS) and non-LOS (NLOS) radio links is necessary to avoid degenerative localization estimation biases.… read more here.

Published in 2020 at "IEEE Transactions on Wireless Communications"

DOI: 10.1109/twc.2020.2967726

Abstract: Discriminating between line-of-sight (LOS) and non-line-of-sight (NLOS) conditions, or LOS identification, is important for a variety of purposes in wireless systems, including localization and channel modeling. LOS identification is especially challenging in vehicle-to-vehicle (V2V) networks… read more here.
