Simulation of NLOS (non-line-of-sight) 3D imaging system
AOPC 2017: Laser Components, Systems, and Applications, 2017This passage studies on theory and scene simulation of NLOS imaging. Based on math and physical properties, a simulation platform is built for a NLOS imaging system, including a femtosecond laser, a scanning galvo system, a lambertian surface, several hidden scenes, an ultrafast photodetector to transfer the intensity of laser echo signal to voltage ...

An evaluation of UWB localization under non line-of-sight (NLOS) propagation
2008 3rd International Symposium on Wireless Pervasive Computing, 2008In this paper we evaluate the statistical performances of the association of a low-complexity of the time of arrival (TOA) estimation algorithm and the location estimation algorithm in a non line-of-sight (NLOS) indoor environment. For that, we choose the time hopping (TH) code and pulse amplitude modulation (PAM) for ultra wideband (UWB) symbols and ...

Detection methodologies to overcome Non line of Sight (NLOS) in Adhoc Networks: A Survey
2019 International Conference on Computer Communication and Informatics (ICCCI), 2019In Vehicular Ad-hoc networks (VANETs) one of the pioneer applications is exchange of emergency messages to identify the location information of the emergency and nonemergency vehicles. But, the presence of obstacles like building infrastructure, trucks and other environmental factors can create Non Line Of Sight (NLOS) which prevents the direct ...

A simulation model of back-projection based non-line-of-sight imaging (NLOS) for resolution analysis
International Conference on Signal Image Processing and Communication (ICSIPC 2021), 2021The problem to image around a corner for objects that are invisible from direct line-of-sight is intriguing as its solution may provide the basis for new methods in various fields. However, most current researches are based on back-projectionrelated methods, of which a quantitative analysis of resolution is missing.

Mobile phone Camera Based Visible Light Communication Using Non-Line-of-Sight (NLOS) Link
2018 International Conference on Network Infrastructure and Digital Content (IC-NIDC), 2018Traditional mobile phone camera based visible light communication (VLC) mainly uses line-of-sight (LOS) link, whose performance will be seriously affected by the blooming effect of complementary metal-oxide-semiconductor (CMOS) camera. In this paper, we introduce a mobile phone camera based VLC using non-line-of-sight (NLOS) link. By using our proposed

Resolving Non Line-of-Sight (NLoS) motion using Speckle
Imaging and Applied Optics 2018 (3D, AO, AIO, COSI, DH, IS, LACSEA, LS&C, MATH, pcAOP), 2018Motion of objects hidden from view is recovered by tracking displacements in speckle patterns produced by the coherently illuminated object. A latent image may additionally be recovered by examining spatial correlations in the speckle pattern.
