Self-Calibration for the Time-of-Arrival Positioning

open access: yesIEEE Access, 2020
Self-calibration of time-of-arrival positioning systems is made difficult by the non-linearity of the relevant set of equations. This work applies dimension lifting to this problem.

Semidefinite Programming Algorithms for 3-D AOA-Based Hybrid Localization

open access: yesIEEE Open Journal of Signal Processing, 2023
By taking different kinds of measurements at the same time, it may be possible to improve the accuracy of target localization or reduce the number of sensors needed.

Local Strong Convexity of Source Localization and Error Bound for Target Tracking under Time-of-Arrival Measurements [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
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.

A comparative analysis of pulse time-of-arrival creation methods [PDF]

open access: yesAstronomy & Astrophysics, 2021
Extracting precise pulse times of arrival (TOAs) and their uncertainties is the first and most fundamental step in high-precision pulsar timing.

Times of arrival (TOA) of signals in the Kerr-MOG black hole

open access: yesGeneral Relativity and Gravitation, 2020
Modified gravity (MOG) theories are alternatives to general relativity (GR) that arose primarily from the need to explain the observed galactic flat rotation curves without invoking the elusive dark matter hypothesized by GR. A well known MOG is the Scalar-Tensor-Vector-Gravity (STVG) developed by Moffat, who has also found a spinning solution called ...

ToA-TS: Time of arrival based joint time synchronization and tracking for mobile underwater systems [PDF]

open access: yesAd Hoc Networks, 2015
Time synchronization and localization are key requirements for distributed underwater systems consisting of numerous low-cost submersibles. In these systems, submersibles are highly resource constrained and typically have limited acoustic communication capability.

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 ...

UWB pulse detection and TOA estimation using GLRT

open access: yesEURASIP Journal on Advances in Signal Processing, 2017
In this paper, a novel statistical approach is presented for time-of-arrival (TOA) estimation based on first path (FP) pulse detection using a sub-Nyquist sampling ultra-wide band (UWB) receiver.

A New Time-Based Algorithm for Positioning Mobile Terminals in Wireless Networks

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
This paper presents a positioning algorithm, named time of arrival to time difference of arrival (TOAD), which computes time-difference-of-arrival (TDOA) measurements from the messages that time-of-arrival (TOA) stations in sight exchange while their ...

Hybrid TOA/AOA Positioning Algorithm Based on GDOP Weighting [PDF]

open access: yesJisuanji gongcheng, 2017
Existing Time of Arrival/Angle of Arrival(TOA/AOA) positioning algorithms based on Wireless Sensor Network(WSN) have low accuracy under the condition that the position of Anchor Nodes(AN) has error.
