Indoor Localization System With NLOS Mitigation Based on Self-Training

Yanru Huang et al.

Summary: This paper presents an indoor localization system that enables non-line-of-sight (NLOS) mitigation based on self-training. The system integrates map, inertial sensors, and ultra-wideband (UWB) measurements through multi-sensory information fusion, and produces and iteratively refines weak labels for UWB measurements. The proposed system reduces NLOS ranging error by 80% and achieves a 90th localization error percentile of 0.5 meters in a complex indoor environment.

Single-Anchor Ultra-Wideband Localization System Using Wrapped PDoA

Feng Ge et al.

Summary: In this paper, a high-accuracy 3D localization scheme based on a single-anchor localization system is proposed. The localization accuracy is improved by expanding the array aperture, addressing the phase wrapping problem through information fusion and using filtering methods. Experimental results show that the proposed system achieves decimeter-level 3D localization accuracy in both indoor and outdoor environments.
