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 ...

Rooftop and indoor reception with transmit diversity applied to DVB-T networks: A long term measurement campaign [PDF]
, 2009 Although transmit Delay Diversity (DD) can provide a gain in indoor and other Non Line of Sight situations (NLOS), it can introduce degradation in rooftop reception. In fact, when the Ricean K factor of the channel is significantly high (e.g.

A new approach to diffraction modelling for line-of-sight (LOS) paths [PDF]
2015 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC), 2015 In this paper, we present a new knife-edge diffraction method based on Bullington method for the terrestrial line-of-sight (LOS) paths. The diffraction loss of our new knife-edge diffraction method is compared with the results obtained from the Delta-Bullington method and the measurement data existing in the literature for sample fixed terrestrial ...

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 ...
