Underwater acoustic time delay estimation based on envelope differences of correlation functions
(MDPI AG, 2019)
This paper proposes underwater acoustic time delay estimation based on the envelope differences of correlation functions (EDCF), which mitigates the delay estimation errors introduced by the amplitude fluctuations of the ...
The effects of resonances on time delay estimation for water leak detection in plastic pipes
(2018-04-28)
In the use of acoustic correlation methods for water leak detection, sensors are placed at pipe access points either side of a suspected leak, and the peak in the cross-correlation function of the measured signals gives ...

Experimental results of a cascadable micropower time delay estimator
(Institution of Engineering and Technology, 2006-10)
Experimental results of a micropower integrated circuit (IC) for the measurement of the relative time delay between two signals are presented. A complete experimental characterisation shows that the IC achieves an accuracy ...
