TDOA Location Accuracy Experiment

open access: yesJournal of Physics: Conference Series, 2019
Abstract TDOA-based wireless signal location technology has been extensively used in engineering applications. Due to the lack of quantitative TDOA location accuracy index benchmark, there is the absence of reference basis in the development of TDOA application system indicators and performance evaluation.

Improved UWB TDoA-Based Positioning Using a Single Hotspot for Industrial IoT Applications

open access: yesIEEE Transactions on Industrial Informatics, 2022
The goal of this article is to investigate ultra wideband localization with time difference of arrival processing at the anchors. We consider scenarios where the anchors are placed very close to each other and the target to be localized is around the ...

Sound Event Detection Using Spatial Features and Convolutional Recurrent Neural Network [PDF]

open access: yes, 2017
This paper proposes to use low-level spatial features extracted from multichannel audio for sound event detection. We extend the convolutional recurrent neural network to handle more than one type of these multichannel features by learning from each of ...

High precision real-time location estimates in a real-life barn environment using a commercial ultra wideband chip [PDF]

open access: yes, 2020
Structural changes lead to an increase in the number of dairy cows and dry sows kept per group. This has consequences in how easily a farmer can supervise his herd and may be detrimental to animal welfare, specifically regarding social relations, time ...

Multi-TDOA Location Algorithm for Three Satellites TDOA Passive Location System

open access: yesJournal of Radars, 2012
Location precision of radiant source is the primary performance of passive location system, and how to improve location precision is an important problem which always attracts attention. In three satellites TDOA (Time Difference Of Arrival) passive location system, location precision of single pulse location is limited by the error of TDOA measure. For

Asynchronous Microphone Array Calibration using Hybrid TDOA Information [PDF]

open access: yesIEEE/RJS International Conference on Intelligent RObots and Systems
Asynchronous microphone array calibration is a prerequisite for many audition robot applications. A popular solution to the above calibration problem is the batch form of Simultaneous Localisation and Mapping (SLAM), using the time difference of arrival ...

An Efficient Constrained Weighted Least Squares Method With Bias Reduction for TDOA-Based Localization

open access: yesIEEE Sensors Journal, 2021
This paper addresses the source location problem by using time-difference-of-arrival (TDOA) measurements. The two-stage weighted least squares (TWLS) algorithm has been widely used in the TDOA location.

Wideband TDoA Positioning Exploiting RSS-Based Clustering

open access: yesSensors, 2023
The accuracy of radio-based positioning is heavily influenced by a dense multipath (DM) channel, leading to poor position accuracy. The DM affects both time of flight (ToF) measurements extracted from wideband (WB) signals—specifically, if the bandwidth is below 100 MHz—as well as received signal strength (RSS) measurements, due to the interference of ...
