Hi,
I need grc/script with energy detector. Algorithm is very simple
sense in each 2 sec
In each interval check the power (energy level) for given frequency
If the energy level is greater than threshold
return 1
else return 0
Please help me, I’m stuck on this. I have checked usrp_spectrum_sense
Hi,
I am working with gnuradio 3.3.0 and now trying to create new block using
gr_modtool.py.
I am able to do following :
cmake
make
sudo make install
sudo ldconfig
after editing header file of bin and lib with .cc file.
Then while using newly created block with GRC I got following error

Hi,
I am using usrp2 and gnuradio 3.3.0.
I want to use benchmark_tx.py as transmitter and benchmark_rx.py as receiver.
so that multiple receiver at distance of around 1 KM should get good signal
strength.
So could you please let me know the best options for tx and rx waveform, so I

1 km is a long distance, so the lower frequency, the less pathloss. Use maximum
tx gain and rx gain. And the distance may highly depend on the environment. Is
there buildings, trees, or just a blank space?

USRP2 daughterboard based on the
Motorola RFIC4. I didn't find "specifications on the "custom daughterboard"" in

Hi,
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.

I want to do energy detection of received signal, And after searching I was

Can anyone explain how this works. How level() method gives the energy level. I
need mathematic behind this function. Is this calculates based
them.
Review Ohms law to see that this is true.
