A Neural-Enhanced Factor Graph-Based Algorithm for Robust Positioning in Obstructed LOS Situations
This paper presents a neural-enhanced probabilistic model and corresponding factor graph-based sum-product algorithm for robust localization and tracking in multipath-prone environments. The introduced hybrid probabilistic model consists of physics-based

Mobile Location with NLOS Identification and Mitigation Based on Modified Kalman Filtering
In order to enhance accuracy and reliability of wireless location in the mixed line-of-sight (LOS) and non-line-of-sight (NLOS) environments, a robust mobile location algorithm is presented to track the position of a mobile node (MN).

An effective indicator for NLOS, nLOS, LOS propagation channels conditions
A simple and physically-based index is proposed to identify among Line-of-Sight (LOS), near Line-of-Sight (nLOS) and Non-Line-of-Sight (NLOS) channel propagation conditions.

NLOS-NeuS: Non-line-of-sight Neural Implicit Surface
Non-line-of-sight (NLOS) imaging is conducted to infer invisible scenes from indirect light on visible objects. The neural transient field (NeTF) was proposed for representing scenes as neural radiance fields in NLOS scenes.

Omnidirectional mobile NLOS identification and localization via multiple cooperative nodes
This paper presents an Omnidirectional mobile target-node (TN) localization technique in nonline-of-sight (NLOS) scenarios. Here, a TN cooperates with base-nodes (BNs) with antenna-arrays to allow them to find its position via time-of-arrival (TOA) and ...

NLOS Identification and Correction Based on Multidimensional Scaling and Quasi-Accurate Detection
In wireless sensor networks, most of the previous NLOS identification is based on error estimation model established by raw data. In this paper, we propose a method of NLOS identification named NIMQ based on multidimensional scaling (MDS) and Quasi ...

A new multi-antenna based LOS - NLOS separation technique
This paper introduces a line-of-sight (LOS) and non-LOS (NLOS) separation technique based on the statistics of the phase difference of two received signals. The phase difference is achieved via a co-installed synchronized two-receiver system.
