Im trying to sense the noise variance when there is no signal. I'm consider a band from 1.2GHz to 1.25GHz. Ofcourse the output is not the same for all frequencies sweeping parts. However when there is no signal i get reading flactuates between 10dB to 20 dB, which, according to the spectrum analyzer, should be around -90dB. While when there is a signal i get readings fluctuates around 80 dB, which in reality much lower than this (around 0dBm)
Therefore i think there is a shift should be done for the output of the FFT. Any body know how much? regards, -- View this message in context: http://old.nabble.com/The-output-of-spectrum_sense-must-be-shifted-to-minus-tp27026849p27026849.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
