The magnitude of the correlation depends on the magnitude of your signal.
The AGC normalizes the signal amplitude before the correlator, so you see
expected behavior. The correlation estimator block expects the input to
have a normalized amplitude.

How close to 1 did you use thresholds for the relative threshold method?
For the relative threshold method I use thresholds between 1-exp(-5)
.. 1-exp(-8).
Cheers.

There is definitely a weird logic with this block.
Let me explain:
Suppose your training sequence is c(t) with energy E=sum_t |c(t)|^2.
The training c(.) is exactly what the parameter "symbols" is in the
correlate block.
Suppose your signal is some scaled version of the training sequence eg,
y(t)
Thank you for your help, Nick, Christoph, and Achilleas!

Even with 1-exp(-15) I get many false positive detections. And it
