Optimal Geometry Analysis for TDOA-Based Localization Under Communication Constraints

IEEE Transactions on Aerospace and Electronic Systems, 2021
The sensor-source geometry has a significant effect on accuracy of source localization problems. In a sensor placement problem, one attempts to optimally place the sensors in the surveillance area so as to optimize a performance criterion.

TDOA Localization With Unknown Signal Propagation Speed and Sensor Position Errors

IEEE Communications Letters, 2020
In time-difference-of-arrival (TDOA) localization systems, the TDOA measurements and range-difference-of-arrival (RDOA) values can be used interchangeably if the signal propagation speed is known.

An improved method to sort and pair TDOA based on the correlation between TDOAs

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
In TDOA passive location system, the situations in which false TDOA combinations arose are sorted. For extracting the correct TDOA combination of the radiant source, an improved method to sort and pair TDOA is proposed in this paper. The method can eliminate the false TDOA combinations which are reduced by sub-PRI(pulse repetition interval) of the ...

TDOA-Based Joint Synchronization and Localization Algorithm for Asynchronous Wireless Sensor Networks

IEEE Transactions on Communications, 2020
This paper presents a joint synchronization and localization algorithm based on the time-difference-of-arrival (TDOA) for asynchronous Wireless Sensor Networks (WSNs), where the positions of anchors are relatively fixed but unknown.

Positioning Algorithms for Cellular Networks Using TDOA

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
In this paper, we investigate the performance of positioning algorithms in wireless cellular networks based on time difference of arrival (TDoA) measurements provided by the base stations. The localization process of the mobile station results in a non-linear least squares estimation problem which cannot be solved analytically.

ASYNCHRONICZNA METODA TDOA

PRZEGLĄD TELEKOMUNIKACYJNY - WIADOMOŚCI TELEKOMUNIKACYJNE, 2015
Przedstawiono nową metode lokalizowania terminali ruchomych MT (Mobile Terminal) w sieciach radiowych, w ktorych stacje bazowe BS (Base Station) pracują asynchronicznie wzgledem siebie. Metoda ta, nazwana ATDOA (Asynchronous Time Difference of Arrival), umozliwia estymacje polozenia MT na podstawie pomiarow roznicy czasow propagacji sygnalow radiowych ...

Anchor-free TDOA self-localization

2011 International Conference on Indoor Positioning and Indoor Navigation, 2011
We present an approach for the localization of passive receiver nodes in a communication network. In our settings the positions of the nodes are unknown. The only source of information is the time when environmental sound or ultrasound signals are received. The discrete signals occur at unknown positions and times, but they can be distinguished.

Estimation of User Location in 4G Wireless Networks Using Cooperative TDoA/RSS/TDoA Method

2014 Fourth International Conference on Communication Systems and Network Technologies, 2014
The 4G wireless network is proposed to integrate various radio access technologies into a common network known as open wireless architecture (OWA), this has led to the idea of cooperative user location estimation, in this paper we have proposed a cooperative TDoA/RSS/TDoA user location estimation method which uses information from two different Radio ...
