Characterization of Non−Line−of−Sight (NLOS) Bias via Analysis of Clutter Topology

, 2016
Clutter-prone environments are challenging for range-based localization, where distances between references and the unlocalized node are estimated using wireless technologies like radio, ultrasound, etc. This is so due to the incidence of Non-Line-Of-Sight (NLOS) distance measurements as the direct path between the twp is occluded by the presence of ...

Accurate Multiclass NLOS Channels Identification in UWB Indoor Positioning System-Based Deep Neural Network

IEEE Access
The accurate distinction between line-of-sight (LOS) and non-line-of-sight (NLOS) propagation channels is paramount for precise distance measurement within ultra-wideband (UWB) indoor localization systems.

On the Application of a Sparse Data Observers (SDOs) Outlier Detection Algorithm to Mitigate Poisoning Attacks in UltraWideBand (UWB) Line-of-Sight (LOS)/Non-Line-of-Sight (NLOS) Classification

Future Internet
The classification of the wireless propagation channel between Line-of-Sight (LOS) or Non-Line-of-Sight (NLOS) is useful in the operation of wireless communication systems. The research community has increasingly investigated the application of machine learning (ML) to LOS/NLOS classification and this paper is part of this trend, but not all the ...
