Hi Marcus,
Thanks for your explanation. Then how should I solve this problem? Should
I install gnuradio first and then install rtl-sdr and gr-osmosdr? Also, if
the problem is what you said, then why don't other people encounter this
problem?
Could you tell me how to install gnuradi
I can fetch rtl-sdr and gr-osmosdr, but failed to build them. I rerun the
build-gnuradio script with --verbose and get the following error:
make[2]:***No rule to make target '../docs/doxygen/filter_generated',
needed by 'docs/doxygen/xml'. Stop.
make[1]:***[docs/doxygen/CMakeFiles/doxygen_target.d
Do you already have the gnuradio and uhd folders? Then just do this:
cd gnuradio
git pull
mkdir build (may give back an error that it already exists, then just go on)
cd build
cmake ..
make
sudo make install
sudo ldconfig
cd
cd uhd
cd host
cmake ..
make
sudo make install
cd

Thanks, Thomas.
I run the command "cmake" with *-DENABLE_BAD_BOOST=True. It seems that the
problem has been solved. But I didn't upgrade the version of Boost. Must I
upgrade the version of Boost? Thanks.*

Hi, all,
I use the usrp_spectrum_sense.py to sweep the TV band from 470MHz to
806MHz. But when I use self.connect(self.u, s2v, fft, c2mag, log, stats),
the FFT bin values I got are all zero.
Also, what's the magnitude of FFT bin value? Thanks.

Hi, Marcus,
Thanks for your reply. Then how should I upgrade the version of Boost? It
seems that the Boost version cannot be upgraded in Ubuntu.

I want to use usrp_spectrum_sense.py to sweep the Hong Kong TV band which
ranges from 470MHz to 806MHz and get every channel's power in dB. Each
channel's frequency band is 8MHz.
Now I'm using USRP2 with TVRX2 daughter board. I have installed the latest
gnuraio and uhd. But when I use the usrp_spe
Hi Jincheng,
Try setting the UHD sample rate to 25e6 and the number of fft bins to 25
which will give you 1e6 Hz per bin. Adding up the magnitude of 8 bins
(1MHz * 8 = 8MHz) will therefore give you the wanted channel power in
decimal format (magnitude).
In case you are confused, I recently updat
Thanks Mike. I'm a little confused. The parameters are listed as follows:
sample-rate:
channel-bandwidth:
freq_step:
fft_size:
You mean that I should set sample-rate be 25e6, channel-bandwidth be 8e6,
freq_step be 8e6 and fft_size be 25?
If we set the fft-size be 25, then which 8 bins I should s
Hi,
For your application, please experiment with the following command:
./usrp_spectrum_sense.py -A TX/RX --fft-size=25 --samp-rate=25e6 --gain=15
--dwell-delay=0.25 --tune-delay=0.25 --channel-bandwidth=8e6 470e6 800e6
Note that 'freq_step' should remain unchanged at '0.75 * usrp_rate' in the
s
Thanks, Mike. Then how should I calculate the power for each channel?
We have analog and digital channels.
