Self-Calibration for the Time Difference of Arrival Positioning [PDF]
The time-difference-of-arrival (TDOA) self-calibration is an important topic for many applications, such as indoor navigation. One of the most common methods is to perform nonlinear optimization.

Time difference of arrival localisation exploiting all available time differences [PDF]
Time difference of arrival geolocation is re-analysed exploiting all available time differences, though sticking to closed-form algorithms based on the minimum number of time differences. The additional information is statistically utilised in a sound way. Error estimates for the resulting position and the Cramer-Rao lower bound are derived.

Propagation Measurement on 2.5 mm NYAF Cable Using Load Matching and TDA [PDF]
In this work, we propose measuring the propagation speed on the transmission medium in the form of a 2.5mm NYAF cable. The method used is load matching and time difference of arrival (TDA).

A Novel Joint TDOA/FDOA Passive Localization Scheme Using Interval Intersection Algorithm
Due to the large measurement error in the practical non-cooperative scene, the passive localization algorithms based on traditional numerical calculation using time difference of arrival (TDOA) and frequency difference of arrival (FDOA) often have no ...

Abstract In many passive localization applications, the reference waveform of the received electromagnetic signals is partly known. The received signals in such scenarios are formulated by modelling the relationship between the received data and the known reference signal waveform and the parameters of interest, such as time ...

Numerical Study of Estimating the Arrival Time of UHF Signals for Partial Discharge Localization in a Power Transformer [PDF]
Partial discharges (PDs) are electrical sparks that occur inside insulation between two conducting electrodes and can lead to the disastrous failure of insulation systems.
