Hi Mike,
Thank you for your reply.
So what if I want to sense with the sensing threshold set by the FCC for
white spaces at -114 dBm or -107 dBm. How does the value of "power_db"
relates to the value I should compare against given the FCC thresholds ?
Kind regards,
Ahmed Saeed.

Hi Ahmed,
Dividing the bin power by the sample rate in the calculation for
noise_floor_db and power_db (lines 286 and 287 of
https://github.com/gnuradio/gnuradio/commit/cc12277f64207ff79a40094268c843e6b3e2d2d3#L0R286)
was done so that the power level stays constant if the sample rate is
increased.
Hi Ahmed,
You will need to use a calibrated rf source to compare your USRP N210 SDR
receiver against and adjust the power_db result (without subtracting the
noise floor result from it) to match. I assume it will be a simple case of
adding or subtracting 'X' db's to the power_db result for each cal
Tom,
that was a good first shot:
I created ~/.gnuradio/config.conf with the lines:
[wxgui]
style = nongl
I even tried
[wxgui]
style = nogl
not any difference
Then I renamed C:\Python27\Lib\site-packages\PyOpenGL-3.1.0a1-py2.7.egg-info
to
C:\Python27\Lib\site-packages\PyOpenGL-3.1.0a1-py2.7
Hi guys,
I'm learning BPSK demodulation recently.
I have learned how to do the carrier synchronization in the file of
digital_costas_loop_cc.c.
so my question is which classes do the symbol synchronization in the gnu
radio.
thank you very much.
