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.

Estimation of pulse heights and arrival times [PDF]
Automatica, 1980 The problem is studied of estimating the arrival times and heights of pulses of known shape observed with white additive noise. The main difficulty is estimating the number of pulses. When a maximum likelihood formulation is employed for the estimation problem, difficulties similar to the problem of estimating the order of an unknown system arise.
