A Novel Method for Asynchronous Time-of-Arrival-Based Source Localization: Algorithms, Performance and Complexity [PDF]

open access: yesSensors, 2020
In time-of-arrival (TOA)-based source localization, accurate positioning can be achieved only when the correct signal propagation time between the source and the sensors is obtained. In practice, a clock error usually exists between the nodes causing the

Low-Complexity Joint Angle of Arrival and Time of Arrival Estimation of Multipath Signal in UWB System [PDF]

open access: yesSensors, 2023
In an ultra-wideband (UWB) system, the two-dimensional (2D) multiple signal classification (MUSIC) algorithms based on high-precision 2D spectral peak search can jointly estimate the time of arrival (TOA) and angle of arrival (AOA).

IEEE 802.15.4 ZigBee-Based Time-of-Arrival Estimation for Wireless Sensor Networks [PDF]

open access: yesSensors, 2016
Precise time-of-arrival (TOA) estimation is one of the most important techniques in RF-based positioning systems that use wireless sensor networks (WSNs).

Times of arrival and gauge invariance [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
We revisit the arguments underlying two well-known arrival-time distributions in quantum mechanics, viz., the Aharonov–Bohm–Kijowski (ABK) distribution, applicable for freely moving particles, and the quantum flux (QF) distribution. An inconsistency in the original axiomatic derivation of Kijowski’s result is pointed out, along with an inescapable ...

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.

Optimal Passive Source Localization for Acoustic Emissions

open access: yesEntropy, 2021
Acoustic emission is a non-destructive testing method where sensors monitor an area of a structure to detect and localize passive sources of elastic waves such as expanding cracks.

Probabilistic Time of Arrival Localization [PDF]

open access: yesIEEE Signal Processing Letters, 2019
In this paper, we take a new approach for time of arrival geo-localization. We show that the main sources of error in metropolitan areas are due to environmental imperfections that bias our solutions, and that we can rely on a probabilistic model to learn and compensate for them.

Dilution of Precision in Positioning Systems Using Both Angle of Arrival and Time of Arrival Measurements

open access: yesIEEE Access, 2020
Dilution of precision (DOP) is a value that can describe the effect on the relationship between measurement error and position determination error.
