|Subject:||[Discuss-gnuradio] How does probe level works|
|Date:||Mon, 19 Aug 2013 10:37:28 +0530|
I am trying to detect the presence of primary user by energy detection. 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.
