Closed Form Approximations for UAV Line-of-Sight Probability in Urban Environments
IEEE Access, 2023 This paper presents a new approach to estimate the probability of line-of-sight (LoS) for unmanned aerial vehicle (UAV) communications. We provide lower and upper bounds on the probability of LoS in terms of what we call the first-building-LoS ...

Non-Line-of-Sight Identification Based on Unsupervised Machine Learning in Ultra Wideband Systems
IEEE Access, 2019 Identification of line-of-sight (LOS) and non-line-of-sight (NLOS) propagation conditions is very useful in ultra wideband localization systems. In the identification, supervised machine learning is often used, but it requires exorbitant efforts to ...
