Predicting Estimated Time of Arrival for Commercial Flights
Proceedings of the 24th ACM SIGKDD International Conference on Knowledge Discovery & Data Mining, 2018Unprecedented growth is expected globally in commercial air traffic over the next ten years. To accommodate this increase in volume, a new concept of operations has been implemented in the context of the Next Generation Air Transportation System (NextGen) in the USA and the Single European Sky ATM Research (SESAR) in Europe.

Enhanced time of arrival estimation with successive cancellation
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003Two methods for accurate estimation of time or angle of arrival that use successive cancellation techniques are presented. The first method performs successive cancellation with a correlation approach used for each iteration. The second method uses the multiple signal identification and classification (MUSIC) approach for each iteration.

Bayesian Estimation of Vessel Destination and Arrival Times
Proceedings of the 12th ACM International Conference on Distributed and Event-based Systems, 20181Predicting the destination port and arrival time of a vessel is challenging, even with the availability of a tremendous amount of trace data. Our goal for this challenge is to build a solution to accurately predict the destination port and arrival times of a given vessel using Bayesian inference and heuristics.

Undersampling for parameter estimation with application to time of arrival estimation
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002This paper deals with the effect of sampling the continuous observations on parameter estimation errors. In particular, we study the problem of estimating the time of arrival (TOA) of a continuous, deterministic signal in noise. For this problem, the sampling procedure transforms the continuous parameter space into a discrete one, resulting in inherent

Time-of-arrival estimation in path attenuation
2009 IEEE 10th Workshop on Signal Processing Advances in Wireless Communications, 2009We consider a time-of-arrival (ToA) estimation in the presence of path attenuation. Maximum correlation (MC) is revisited and maximum likelihood (ML) is newly derived to estimate the ToA. It reveals that for low effective bandwidth, short distance and large path loss exponent, the ML has a smaller error variance than the MC.

Implicit estimation of sound-arrival time
Nature, 2003In perceiving the sound produced by the movement of a visible object, the brain coordinates the auditory and visual input1,2,3 so that no delay is noticed even though the sound arrives later (for distant source objects, such as aircraft or firework displays, this is less effective).

Time-of-Arrival Estimation in Mobile Tour Guides
2013In recent years advanced car navigation systems have emerged as a key tool for commuters. For tourists and visitors, analogous mobile tour guides are equally important when exploring urban and outdoor spaces. During the development of a mobile tour guide designed specifically forhikers and cyclists the need for route planning based on individualized ...

Bias free estimation of the variance of time of arrival differences
ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1985In the frequency domain estimation of Time of Arrival differences, phase data of the cross-spectrum may show correlation between frequency bins due to either insufficient time-bandwidth product or the use of a nonrectangular window on the input signal samples.

Phase recovery for time of arrival estimation in the presence of interference
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015Time of arrival is a commonly used mechanism for geolocation. In many environments, multipath propagation of RF signals limits accuracy. Wide bandwidths reduce the impact of multipath propagation, but frequently results in interference from other devices. When the bandwidth is assembled from several measured sub-bands, there is an additional difficulty

Detection and time-of-arrival estimation of underwater acoustic signals
2016 IEEE 17th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2016We focus on detection and time-of-arrival (ToA) estimation of underwater acoustic signals of unknown structure. The common practice to use a detection threshold may fail when the assumed channel model is mismatched or when noise transients exist. We propose to detect and evaluate the ToA by labeling samples of observed data as ‘signal’ or ‘noise’. Then,
