A semidefinite programming approach for robust elliptic localization

no code implementations28 Jan 2024 Wenxin Xiong, Jiajun He, Zhang-Lei Shi, Keyuan Hu, Hing Cheung So, Chi-Sing Leung

This short communication addresses the problem of elliptic localization with outlier measurements, whose occurrences are prevalent in various location-enabled applications and can significantly compromise the positioning performance if not adequately handled.

Robust time-of-arrival localization via ADMM

no code implementations15 Jun 2023 Wenxin Xiong, Christian Schindelhauer, Hing Cheung So

This article considers the problem of source localization (SL) using possibly unreliable time-of-arrival (TOA) based range measurements.

Globally Optimized TDOA High Frequency Source Localization Based on Quasi-Parabolic Ionosphere Modeling and Collaborative Gradient Projection

no code implementations10 Feb 2023 Wenxin Xiong, Christian Schindelhauer, Hing Cheung So

We investigate the problem of high frequency (HF) source localization using the time-difference-of-arrival (TDOA) observations of ionosphere-refracted radio rays based on quasi-parabolic (QP) modeling.

Two Efficient and Easy-to-Use NLOS Mitigation Solutions to Indoor 3-D AOA-Based Localization

no code implementations21 Jul 2021 Wenxin Xiong, Joan Bordoy, Andrea Gabbrielli, Georg Fischer, Dominik Jan Schott, Fabian Hoeflinger, Johannes Wendeberg, Christian Schindelhauer, Stefan Johann Rupitsch

This paper proposes two efficient and easy-to-use error mitigation solutions to the problem of three-dimensional (3-D) angle-of-arrival (AOA) source localization in the mixed line-of-sight (LOS) and non-line-of-sight (NLOS) indoor environments.

Neurodynamic TDOA localization with NLOS mitigation via maximum correntropy criterion

no code implementations14 Sep 2020 Wenxin Xiong, Christian Schindelhauer, Hing Cheung So, Junli Liang, Zhi Wang

In this paper, we exploit the maximum correntropy criterion (MCC) to robustify the traditional time-difference-of-arrival (TDOA) location estimator in the presence of non-line-of-sight (NLOS) propagation conditions.

Maximum correntropy criterion for robust TOA-based localization in NLOS environments

no code implementations13 Sep 2020 Wenxin Xiong, Christian Schindelhauer, Hing Cheung So, Zhi Wang

We investigate the problem of time-of-arrival (TOA) based localization under possible non-line-of-sight (NLOS) propagation conditions.

TDOA-based localization with NLOS mitigation via robust model transformation and neurodynamic optimization

no code implementations22 Apr 2020 Wenxin Xiong, Christian Schindelhauer, Hing Cheung So, Joan Bordoy, Andrea Gabbrielli, Junli Liang

This paper revisits the problem of locating a signal-emitting source from time-difference-of-arrival (TDOA) measurements under non-line-of-sight (NLOS) propagation.
