where [S1 ⋆S2](t) represents the cross-correlation between the signals at receivers as a function of time delay, t. Tmax is the maximum possible absolute delay and can be calculated as Dc , where D is the distance between the receivers....
This paper presents the utilization of super resolution algorithms for the indoor positioning applications in order to estimate Time difference of Arrival (TDOA) and distances using OFDM transceiver. Optimal reduction in Distance Measurement Error (DME) is achieved. We have utilized OFDM/SC-DFE signal...

There are also applications within chemistry for deducing molecular 3D structure given inter-atom distance measurements and within machine learning and visualization of data, where only similarity measures between sample points are provided. Several interesting geometric problems arise in this area, eg ...
How to Calculate Estimated Time of Arrival While calculating the ETAs, multiple factors are taken into consideration. These include: Distance between origin and destination The average speed of the vessel Number of Port of Calls Climate and weather conditions ...

An important property of a hyperbola is that the absolute value of the distance difference Δd from each of the foci to a point on the hyperbola is constant, i.e., $$\Delta d=2a=\mathrm{constant}.$$ (5) Therefore, introducing the Eq. (5) into Eq. (2), the parameter a then ...
Problems associated with the use of intersecting hyperboloids for passive source localization from time-of-arrival difference signals are discussed. A closed-form solution for source location is presented given time-of-arrival difference measurements when the distance from the source to any arbitrary ref...
atherefore, the time interval between the arrival of the electromagnetic signal and the thunder is essentially determined by the distance to the channel divided by the speed of sound. This “flash-to-bang” time is approximately 3 seconds per kilometer of distance to the closest audible point on...
Of course, we then have a long path DB. If we move over a little to the right, to E, we slightly increase the first distance, but we greatly decrease the second one, and so the total path length, and therefore the travel time, is less. How can we find the point C for which ...
