Improved Weighted Least Squares Algorithm for Hybrid AOA and TDOA Localization
Symposium on Software Performance, 2023This paper develops a new hybrid AOA and TDOA localization algorithm. The most promising hybrid AOA and TDOA localization algorithm currently available is a weighted least squares (WLS) estimator, in which the AOA measurements are multiplied by the TDOA ...

Accurate estimation of time difference of arrival (TDOA) between sensors is a fundamental problem in various applications of sensor networks. In this letter, a novel algorithm is proposed to estimate TDOAs based on low-rank essence of a TDOA matrix, whose entry $(i,j)$ denotes TDOA value between sensors $i$ and $j$ with respect to a ...

TDOA Positioning Based on Factor Graphs
2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006In this paper, we introduce a factor graph based positioning algorithm in wireless cellular networks using time difference of arrival (TDoA) measurements provided by the base stations. The localization process of the mobile station results in a non-linear estimation problem which cannot be solved analytically.

TDOA Localization in Asynchronous WSNs
2014 12th IEEE International Conference on Embedded and Ubiquitous Computing, 2014This paper proposes a procedure based on time-difference of arrival measurements to localize a blind node in an asynchronous network where a set of nodes with known position is present. The proposed method computes the time-difference of arrival of each transmitted signal to any pair of receiving nodes in order to get rid of the unknown transmission ...

A Maximum-Likelihood TDOA Localization Algorithm Using Difference-of-Convex Programming
IEEE Signal Processing Letters, 2021A popular approach to estimate a source location using time difference of arrival (TDOA) measurements is to construct an objective function based on the maximum likelihood (ML) method.

Calibration-free TDOA self-localisation
Journal of Location Based Services, 2013We present an approach for the localisation of passive receiver nodes in a communication network. 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.

Selection of Reference Base Station for TDOA-based Localization in 5G and Beyond IIoT
2022 IEEE Globecom Workshops (GC Wkshps), 2022Location awareness is fundamental for several applications operating in fifth generation (5G) and beyond wireless networks. To provide accurate localization in 5G networks, time difference-of-arrival (TDOA) measurements are commonly employed.

Wireless Localization Using TDOA-DOA
International Journal on Communications Antenna and Propagation (IRECAP), 2015This paper describes a hybrid estimate DOA/TDOA (Direction of Arrival/Time Difference of Arrival) location estimation method based on the Multiple Signal classification MUSIC algorithm. The method utilized estimates the Direction (Angle) of Arrival (DOA) and Time Difference of Arrival (TDOA).
