Hi everyone,
Following is the link to the my GSOC proposal for the project Wireless
Networks in-the-loop.
I am looking forward to feedback on the proposal.

Hi all,
I am using ubuntu 13.04 and GNURADIO 3.7.
In project https://github.com/BogdanDIA/gr-dvbt , in reference_signals_impl.cc
in /lib, I add inside one of the functions:
fftw_complex *in2, *out2;
out2 = (fftw_complex*) fftw_malloc(NFFT*2*sizeof(fftw_complex));
in2 = (fftw_complex*)
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
The (F) was meant to say:
Use FFTW3_LIBRARIES if you want to use the double precision version,
use FFTW3F_LIBRARIES if you want the single (float, 'F') precision
version of the library.
Since you're using
fftw_malloc (without f suffix), you're trying
Thanks for quick reply!
It does not work even if I use float precision as
fftwf_complex *in2, *out2;
out2 = (fftwf_complex*) fftwf_malloc(NFFT*2*sizeof(fftwf_complex));
in2 = (fftwf_complex*) fftwf_malloc(NFFT*2*sizeof(fftwf_complex));
I attach cmake files. It would be nice of you if you take a
-BEGIN PGP SIGNED MESSAGE-

Your main CMakeLists.txt is still looking for the double FFTW3.
replace
find_package(FFTW3)
by
find_package(FFTW3f)
and use the FindFFTW3f.cmake from the gnuradio source tree.
You'll have to replace all occurences of FFTW3_ by FFTW3F_ in your
CMake
It does not work anyway. I attach again files.

You need to add the FFTW3F_LIBRARIES to the target_link_libraries.

I added target_link_libraries(gnuradio-dvbt ${Boost_LIBRARIES}

But that does not help.

Then I'm out of clues.
You have basically the same setup up as gr-fft now. Your module
*should* be linked against FFTW3f. Are you sure you replace
fftw_malloc and fftw_whatever by fftwf_whatever in your C++ code?

By the way I am working with GR 3.6.5,
The precise question is as following, If I am instantiating a usrp_sink and
usrp_source from inside my python script and I want at some point in time
modify one of its proprieties from inside my C++ custom block, would that
make sense and work ?
Or I must
Great thanks to all of you here and in melange! The content below is
updated according to the advises above: 1.More details in time
synchronization and burst extraction; 2.More details in using streamed tag
to get more stable frequency resetting; 3.More details in frequency
correlation; 4.A state
Hi all,
Sorry to introduce so late, but I want to share my GSoC 2014 proposal
about improving PyBOMBS. It is available on Github [1], and I mentioned
the link in Google Melange. I was busy with several urgent tasks and
risks missing the GSoC. Hope now is still in time.
I would like to thank for
I have updated my gnuradio installation via pybombs today.

crashes with:

Sorry for the delayed response. My code is all written in C++; I am not

I cannot see anything being wrong with USB. I tried different Kernels,
different Dongles and they all fail. However booting my live DVD and
starting gqrx (32bit) works.
It looks like some incompatibility between the latest gqrx and my
systems :-(

This does not work. GQRX depends on gr-osmosdr and wont compile without it.

Make sure you have the latest version of rtl-sdr library and gr-osmosdr.
There was a change somewhere and if you have one version more recent
than the other, it can cause issue. So rebuild librtlsdr , then
rebuild gr-osmosdr to use it, then rebuild gqrx.
