Location errors in time of arrival (TOA) and time difference of arrival (TDOA) systems [PDF]

open access: yes, 1977
It is shown that the covariance matrix of object location errors is identical for time of arrival (TOA) and time difference of arrival (TDOA) systems if the inverse of the covariance matrix of TOA (TDOA) errors is used as a weighting matrix. Also, with this weighting the location errors statistics do not depend on the particular difference pairs in the

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

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).

Multi-Source Localization Using Time of Arrival Self-Clustering Method in Wireless Sensor Networks

open access: yesIEEE Access, 2019
The localization of multiple signal sources based on Time Of Arrival (TOA) measurements in wireless sensor networks is investigated in this paper. When the signal sources cannot be distinguished by their signatures or other unique characteristics, the ...

Robust time-of-arrival localization via ADMM [PDF]

open access: yesJournal of the Franklin Institute, 2023
This article considers the problem of source localization (SL) using possibly unreliable time-of-arrival (TOA) based range measurements. Adopting the strategy of statistical robustification, we formulate TOA SL as minimization of a versatile loss that ...

TOA Estimation of Indoor Localization by Wi-Fi Signal Based on Waveform Edge Detection [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2022
To locate the target indoor precisely, it was important to investigate on the Wi-Fi based indoor localization parameter, namely, time of arrival(TOA).The main weakness of primary TOA estimation methods were estimation bias, complex algorithm,and lack of ...
