Non-line-of-sight (NLOS) error mitigation for the time-of-arrival (TOA) localization has been extensively studied, but these methods cannot be directly applied for the time-difference-of …
An unknown-position sensor can be localized if there are three or more anchors making time- of-arrival (TOA) measurements of a signal from it. However, the location errors can be very …

Accurate localization is critical to facilitate location services for Internet of Things (IoT). It is particular challenging to provision localization based on nonline-of-sight (NLOS) signals …
K Yu, YJ Guo - IEEE Transactions on Vehicular Technology, 2008 - ieeexplore.ieee.org
Nonline-of-sight (NLOS) propagation is one of the challenges in radio positioning. Significant attention has been drawn to the mitigation of the NLOS effect in recent years. This …
