Gravitational Wave Burst Source Direction Estimation using Time and Amplitude Information [PDF]
, 2008 In this article we study two problems that arise when using timing and amplitude estimates from a network of interferometers (IFOs) to evaluate the direction of an incident gravitational wave burst (GWB).

Two-Step Time of Arrival Estimation for Pulse-Based Ultra-Wideband Systems
EURASIP Journal on Advances in Signal Processing, 2008 In cooperative localization systems, wireless nodes need to exchange accurate position-related information such as time-of-arrival (TOA) and angle-of-arrival (AOA), in order to obtain accurate location information.

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.

An Ultra-fast DOA Estimator with Circular Array Interferometer Using Lookup Table Method [PDF]
, 2015 The time-consuming phase ambiguity resolution makes the uniform circular array (UCA) interferometer not suitable for real-time direction-of-arrival (DOA) estimation. This paper introduces the lookup table (LUT) method to solve this problem.

Dead Time Compensation for High-Flux Ranging [PDF]
, 2019 Dead time effects have been considered a major limitation for fast data acquisition in various time-correlated single photon counting applications, since a commonly adopted approach for dead time mitigation is to operate in the low-flux regime where dead
