[Discuss-gnuradio] mathematics behind probe.level( )

[dilip thapa]

Hi,

I want to do energy detection of received signal, And after searching I was advised to use probe block to do the sense. (gr.probe_avg_mag_sqrd_f). 

Can anyone explain how this works. How level() method gives the energy level. I need mathematic behind this function. Is this calculates based on FFT or what?

 

Please help

 

and please add  my email on reply.(address@hidden)
