Uncover the Power of Multipath : Detecting NLOS Drones Using Low-Cost WiFi Devices
… focus on detecting drones using line-of-sight (LOS) RF signals which are less noisy as compared to their non-LOS (NLOS) counterparts. To the best of our knowledge, there is no existing cost-effective solution for the general public to enable non-LOS(NLOS) detection for drone privacy invasion, …

Using Light Detection and Ranging (LiDAR) Imagery to Model Radio Wave Propagation
… data set for modeling near line-of-sight (LOS) propagation at higher frequencies, specifically 27.810 GHz. than a USGS digital elevation model (DEM). In addition, the study tested for significant differences in LiDAR elevation data created at various resolutions ranging from 1 to 100 …

Vision-Enhanced Communications: On the Benefits of NLOS/LOS Knowledge in Wireless Systems
… about one such property, that of line-of-sight (LOS)/non-line-ofsight (NLOS) states, is the central focus of this work. A generalized signal detection framework is presented for a vision sensor-aided receiver operating in a binary continuous-time Markov chain (CTMC) channel environment wherein …
