Improving the performance of the time-of-arrival estimator in MIMO systems
2012 6th International Conference on Signal Processing and Communication Systems, 2012With the objective of minimizing the Cramer-Rao lower bound (CRLB) of the time of arrival (ToA) estimator, we propose a method to improve the accuracy of ToA estimate for multiple-input multiple-output (MIMO) systems when the transmitted signal can be pre-processed.

F-Wave Decomposition for Time of Arrival Profile Estimation
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007F-waves are distally recorded muscle responses that result from "backfiring" of motor neurons following stimulation of peripheral nerves. Each F-wave response is a superposition of several motor unit responses (F-wavelets). Initial deflection of the earliest F-wavelet defines the traditional F-wave latency (FWL) and earlier F-wavelet may mask F ...

Maximum Likelihood time of arrival estimation for ultrawideband signals
2007 9th International Symposium on Signal Processing and Its Applications, 2007In this contribution, we investigate maximum likelihood (ML) techniques for the estimation of time of arrival (ToA) for ultrawideband (UWB) propagation signals. Using the same methodology as [1], which was introduced for the multichannel estimation, we derive the ML criteria for the UWB ToA parameters estimation and we apply a denoising frequency ...

Estimated time of arrival and debiasing the time saving bias
Ergonomics, 2015The time saving bias predicts that the time saved when increasing speed from a high speed is overestimated, and underestimated when increasing speed from a slow speed. In a questionnaire, time saving judgements were investigated when information of estimated time to arrival was provided.

Port Call Optimization by Estimating Ships’ Time of Arrival
2018Ships’ estimated arrival times command an optimized port call and thus the heartbeat of every sea port. Various factors influence the waiting times of vessels at anchorage. Occupied berths or tide dependencies are just some of the factors leading to long waiting times before entering the port.

Time of arrival based location estimation for cooperative relay networks
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010In this paper, we investigate the performance of a cooperative relay network performing location estimation through time of arrival (TOA). We derive Cramer-Rao lower bound (CRLB) for the location estimates using the relay network. The analysis is extended to obtain average CRLB considering the signal fluctuations in both relay and direct links.

Estimating time of arrival in heavy weather conditions
Guidance, Navigation, and Control Conference and Exhibit, 1999This paper investigates’the problem of computing an aircraft’s Estimated Time of Arrival (ETA) at the runway given that the aircraft is likely to maneuver around hazardous weather. The problem is solved for the TRACON airspace, and specifically to assist the Center-TRACON Automation System (CTAS) to establish an aircraft’s ETA under heavy weather ...
