Hi, all,
Has anyone used usrp_spectrum_sense.py to sweep frequency band and get the
channel's power? I need your help.
When I use "self.connect(self.u, s2v, fft, c2mag, log, stats)", the FFT bin
values I got are all zero. But if I use "self.connect(self.u, s2v, fft,
c2mag, stats)", some FFT bin v

Hi, Omer,
That's exactly what I want to do. But I use the usrp_spectrum_sense.py to
get each channel's power and then compare with the threshold. Maybe you
should try the usrp_spectrum_sense.py.

freq_step is 8MHz. Anyone has any ideas about how to use
usrp_spectrum_sense.py to calculate each channel's power?

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.

Hi, Sid,
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, Ralph,
When I enter the gnuradio/build and run the command ”cmake ...”, an
warning “*Found a known bad version of Boost* (v104601). Disabling”
occurred.
I’m not sure whether this warning will affect the fllowing commad
“make”.

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
Hi all,
I use build-gnuradio to install gnuradio and uhd. But the error meassgae
"Building rtl-sdr...gr-osmosdr build apparently failed" occurred. Has anyone
successfully installed gnuradio and uhd using build-gnuradio script? Hope
you can help me. Thanks.

rnatively, If I want to configure USRP2, how should I install
gnuradio and uhd? I think the build-gnuradio script is the easiest, but I
failed.
Best regards,
Jincheng Zhang

Hi, Josh,
The complete verbose is as follows:
Traceback(most recent call last):
File "./usrp_spectrum_sense.py", line 277, in

Dear all,
I have installed the latest version of uhd by running the script
build-gnuradio. But when I run the python scirpt usrp_spectrum_sense.py,
the error message occured. I'm using USRP2. Anyone has any ideas about this
problem? Thanks a lot.
