Root-MUSIC-based joint TOA and DOA estimation in IR-UWB
Tongxin xuebao, 2014 The parameters can be estimated via two-dimensional (2D) multiple signal classification (MUSIC) algorithm, in which the two-dimensional spectral peak searching, however, requires much higher computational complexity.

A Model on Indoor Localization System Based on the Time Difference Without Synchronization
IEEE Access, 2018 Localization has emerged as an attractive solution to enable new business models that rely on location-based services in wireless networks for communication, sensing, and control. In particular, time difference-of-arrival (TDOA) is one of the widely used

What is Time in Quantum Mechanics?
, 2014 Time of arrival in quantum mechanics is discussed in two versions: the classical axiomatic "time of arrival operator" introduced by J. Kijowski and the EEQT method. It is suggested that for free particles the two methods may lead to the same result.

Nonnegative deconvolution for time of arrival estimation
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004 The interaural time difference (ITD) of arrival is a primary cue for acoustic sound source localization. Traditional estimation techniques for ITD based upon cross-correlation are related to maximum-likelihood estimation of a simple generative model.
