$ /opt/gnuradio/bin/bbn_80211b_rx.py -f 2.437G -v -b Bits Per Encoded Sample = 8 adc frequency = 64000000 decimation frequency = 16 input_rate = 4000000 gain = 45.0 desired freq = 2437000000.0 baseband frequency 2432000000.0 dxc frequency -5000000.0 Samples per data bit = 8 >>> gr_fir_ccf: using SSE The first thing I notice is that it seems to be giving me 2.432G instead of 2.437G? Also the dxc frequency is negative. And of course, no packets get printed out.
From just looking at what is being printed out, you may want to adjust
+5MHz from your baseband frequency. It looks like it tunes to your baseband frequency +5MHz which causes an image to be correlated against a 5MHz local oscillator (dxc?). Then again, I've never worked with this software before so it is just a guess from what I can see. Brian
