Hi, Normally, this kind of delay detection is done using cross-correlation (or > some more applicable variant thereof such as MRC). Note also that a delay > will give a frequency-dependent phase shift, so you may wish to use a delay > block rather than phase shift if your signal is broadband (although I must > admit I don't know what the phase shift block does internally). > > Yes you're right about the cross-correlation and I did that for my experiments where I couldn't see any relation between the maximum correlation value and the time-lag between the signals. Have attached those values (for different runs) that I noted down.
[image: Inline image 1] Can I know how to use these values to implement the delay block in the GRC? Thanks.
