Hi,

 

I need grc/script with energy detector. Algorithm is very simple

1. sense in each 2 sec
2. In each interval check the power (energy level) for given frequency
3. If the energy level is greater than threshold
1. return 1
2. else return 0

 

Please help me, I’m stuck on this. I have checked usrp_spectrum_sense.py but can’t get any clue.

 

Thanks in advance.

Dilip

There's a probe_avg_mag**2 block, which computes the instantaneous power and runs it through an averager.  You can then probe that at whatever
  rate you want in a Python routine.
