More and more applications of location-based services lead to the development of indoor
positioning technology. Wi-Fi-based indoor localization has been attractive due to its …

Accurate indoor localization remains a significant challenge, primarily due to multipath and
non-line-of-sight (NLoS) propagation conditions in complex indoor environments. Traditional …

Indoor positioning systems have received increasing attention for supporting location-based
services in indoor environments. Wi-Fi based indoor localisation has become attractive due …

Localization is particularly challenging when the environment has mixed line-of-sight (LOS)
and non-LOS paths and even more challenging if the anchors' positions are also uncertain …

In this paper, we consider a time-varying optimization approach to the problem of tracking a
moving target using noisy time-of-arrival (TOA) measurements. Specifically, we formulate the …

Wireless sensing technology allows for non-intrusive sensing without the need for physical
sensors worn by the target, enabling a wide range of applications, such as indoor tracking …

Sparse channel estimation problem is one of challenge technical issues in broadband
wireless communications. Square error criterion based adaptive sparse channel estimation …

We consider robust mobile location estimation using range measurements from multiple
base stations under probabilistically mixed line-of-sight (LOS)/non-LOS (NLOS) conditions …

For positioning system based on wireless sensor networks, NLOS errors are one of the main
factors to degrade localization performance of an algorithm, about which lots of research …

In complex indoor environments, target tracking performance is impacted by non-line-of-
sight (NLOS) noises and other measurement errors. In order to fix NLOS errors, a Double …
