Hi all,
I use the usrp_spectrum_sense.py in the gnuradio-example to do the spectrum
sensing. The gain is 45dB. I got the mag_squared of the fft output (m.data). I
think that I can treat it as power. I would like to draw the spectrogram. Does
any one know the unit of the m.data in the usrp_spectrum_sense.py ? I use the
10*log(mag_squared) and the results are between 50-100dB. I think something is
wrong. The value is too large.
Thank you!
Jane
