The accuracy of the paramedic's estimated time until arrival (ETA) to an emergency department has never been studied. Two hundred and eighty paramedic runs were prospectively studied in a suburban, residency-affiliated emergency department. The average ETA was 7.39 +/- 3.72 minutes.

Performance of ML estimators for time of arrival estimation
Gateway to 21st Century Communications Village. VTC 1999-Fall. IEEE VTS 50th Vehicular Technology Conference (Cat. No.99CH36324), 1999The performance of a set of high-resolution algorithms for estimating the time of arrival of a band-limited signal received on a multipath channel is compared. The algorithms investigated use an increasing degree of known information about the channel and estimate the unknown elements using the maximum-likelihood criterion.

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.

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.

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

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,

Efficient time of arrival estimation in the presence of multipath propagation
The Journal of the Acoustical Society of America, 2013Most of acoustical experiments face multipath propagation issues. The times of arrival of different ray paths on a sensor can be very close. To estimate them, high resolution algorithms have been developed. The main drawback of these methods is their need of a full rank spectral matrix of the signals.

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 ...
