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.

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.

Time‐difference‐of‐arrival and frequency‐difference‐of‐arrival estimation for signals with partially known waveform

open access: yesIET Signal Processing, 2023
Abstract In many passive localization applications, the reference waveform of the received electromagnetic signals is partly known. The received signals in such scenarios are formulated by modelling the relationship between the received data and the known reference signal waveform and the parameters of interest, such as time ...

Contributed Review: Source-localization algorithms and applications using time of arrival and time difference of arrival measurements [PDF]

open access: yesReview of Scientific Instruments, 2016
Locating the position of fixed or mobile sources (i.e., transmitters) based on measurements obtained from sensors (i.e., receivers) is an important research area that is attracting much interest. In this paper, we review several representative localization algorithms that use time of arrivals (TOAs) and time difference of arrivals (TDOAs) to achieve ...

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 ...

A Two-Stage Method for Short-Wave Target Localization Using DOA and TDOA Measurements

open access: yesIEEE Access, 2023
The ionosphere can make the short-wave source localization problem further non-linear, leading to a complicated solution process. This paper proposed a coordinated positioning algorithm based on the ionospheric virtual height (IVH) model to jointly ...
