I've already checked usrp_spectrum_sense.
I have two points:
1. usrp_fft: does this file still exist ? because i cannot find it. but i
think, it just give you the same results as usrp_spectrum_sense without
tuning the frequency band.
2. You meant by using "quiet time", is to

I implemented an energy detector on the GNU Radio by using a GPU at my old
job.
We used an FFT based method which is not uncommon. What you do is FFT the
data and then compute the PSD. Do this in overlapping blocks (e.g. 12.5%,
50%, etc). You could optionally use a window too. Then, with the
