Robust localization in wireless networks from corrupted signals

open access: yesEURASIP Journal on Advances in Signal Processing, 2021
We address the problem of timing-based localization in wireless networks, when an unknown fraction of data is corrupted by non-ideal propagation conditions.

Propagation Measurement on 2.5 mm NYAF Cable Using Load Matching and TDA [PDF]

open access: yesE3S Web of Conferences, 2021
In this work, we propose measuring the propagation speed on the transmission medium in the form of a 2.5mm NYAF cable. The method used is load matching and time difference of arrival (TDA).

A Novel Joint TDOA/FDOA Passive Localization Scheme Using Interval Intersection Algorithm

open access: yesInformation, 2021
Due to the large measurement error in the practical non-cooperative scene, the passive localization algorithms based on traditional numerical calculation using time difference of arrival (TDOA) and frequency difference of arrival (FDOA) often have no ...

Numerical Study of Estimating the Arrival Time of UHF Signals for Partial Discharge Localization in a Power Transformer [PDF]

open access: yesJournal of the Korean Institute of Electromagnetic Engineering and Science, 2018
Partial discharges (PDs) are electrical sparks that occur inside insulation between two conducting electrodes and can lead to the disastrous failure of insulation systems.

Experimental measurement of time difference of arrival [PDF]

open access: yes2016 17th International Radar Symposium (IRS), 2016
In this paper is described an experimental passive localization system based on SDR (Software Defined Radio) components. This system is designed to measure Time Differences of Arrival (TDOA) of radar pulses between two platforms. For a TDOA system, time error between the two receivers must be kept very low, which requires a very accurate way to ...

Fusion Localization Algorithm Based on Robust IMM Model Combined with Semi-Definite Programming

open access: yesActuators, 2022
With the continuous development of wireless sensor network (WSN) technology, WSN has gradually become one of the key technologies of the Internet, and is widely used in indoor target location technology. However, the obstacles will have a great influence

Closed-Form Formulae for Time-Difference-of-Arrival Estimation [PDF]

open access: yesIEEE Transactions on Signal Processing, 2008
For a positioning system with L sensors, a maximum of L(L-1)/2 distinct time-difference-of-arrival (TDOA) measurements, which are referred to as the full TDOA set, can be obtained. In this paper, closed-form expressions regarding optimum conversion of the full TDOA set to the nonredundant TDOA set, which corresponds to (L-1) TDOA measurements with ...

Time Difference of Arrival Extraction from Two-Way Ranging

open access: yesCoRR, 2022
Two-Way Ranging enables the distance estimation between two active parties and allows time of flight measurements despite relative clock offset and drift. Limited by the number of messages, scalable solutions build on Time Difference of Arrival to infer timing information at passive listeners.

A Fractional Programming Method for Target Localization in Asynchronous Networks

open access: yesIEEE Access, 2018
In this paper, we address the target device localization problem in the asynchronous networks. For the purpose of saving power resources, the target device is not synchronized with the anchor nodes, but is only required to listen to the signals ...

Performance Comparison of ToA and TDOA Based Tracking In Underwater Multipath Environments Using Bernoulli Filter

open access: yesPolish Maritime Research, 2023
Underwater localization and tracking is a challenging problem and Time-of-Arrival and Time-Difference-of-Arrival approaches are commonly used. However, the performance difference between these approaches is not well understood or analysed adequately ...
