How do you find the time delay between two signals?

τdelay=argmax ((f∗g)(t)), this will estimate the time offset where the signals are best aligned.

How do you calculate time delay between two signals in Matlab?

d = finddelay( x , y ) returns an estimate of the delay d between input signals x and y . Delays in x and y can be introduced by prepending zeros. d = finddelay( x , y , maxlag ) uses maxlag to find the estimated delay(s) between x and y .

What is delay time estimation?

Time delay estimation (TDE) is the problem of estimating the time delay between two received signals which have originated from same transmitter. ¹. This estimation problem is of fundamental importance in radar signal processing for detecting the presence of targets and identifying radar transmitters.

How do you find time delay using cross-correlation?

For delay analysis, correlation in the time domain is widely used. The correlation function plots the similarity between two signals for all possible lags τ. The peak of the correlation function occurs at the lag with the best similarity between the two signals, i.e. the estimated delay.
