Hi all,
When I set the decimation of a fir_filter or integrate block with float
input and output to 262144 or above, gnuradio crashes with a segfault.
With complex inputs and outputs I get a segfault above 524288.
with short inputs and outputs it is at decimation 131072.
This seems to be the c
I don't know much about this toolkit, but you can find our gr-cdma toolkit
on github.
It is a full blown (and fully parameterised by the user) cdma system with
acquisition/tracking/adaptive modulation/coding, etc.

I've posted some notes from the working group call that was held yesterday
- they are available at:
http://gnuradio.org/redmine/projects/gnuradio/wiki/Call20150211
Additionally, the main item that came out of the call was that we should
clearly document what use cases require changes to mainline G
If your options block is set to "qt-gui" you can use qt-gui and only qt-gui
blocks in your flowgraph. Likewise, if your options block is set to
"wx-gui" you can use wx-gui and only wx-gui blocks in your flowgraph.
Since wx-gui blocks are working for you, I can conclude your options block
is set to
Because your blocks are WX-GUI. Changing the parameter only changes the
"boilerplate" code that is emitted. So, if you're using QT-GUI
boilerplate with WX-GUI blocks, that won't work.

Marcus,
Thanks for the assistance. I changed the display for qt-gui to wx-gui and
it now runs correctly. My only remaining concern is why doesn't it work
with qt-gui. I have QT4 installed.

Thank you all for looking at this.
setting the GRC_BLOCKS_PATH and then using grcc works fine for me, but not
with the grc companion.
Thanks,
Murray

Hi All,
I just came across this talk "Spread Spectrum Techniques in GNU Radio" in GNU
Radio Conference ‘14. The presentation (

tells about the Spread spectrum toolkit developed. I am trying to find the

I created an issue [1] for
Farida,
Nice work.
I believe your students will also be interested in IEEE spectrum sharing
challenge [1].

...and it's a common technique. You can easily demod FM radio this way,
even without a filter (although it'll be pretty noisy) and I've seen
people demod DVB-T this way (probably with f
Fraida,
this is very, very cool! As a former university guy myself, I very much
enjoy people getting creative and thinking outside of the "industry
standard software" box.
Any chance you can have the students directly answer these questions on
the mailing list, and in time? :D
Another suggestion
Thanks for your answer Tom and sorry for the delay replying to you.
I tried setting the environment variable GRC_HIER_PATH but it didn't make
any difference. I also tried setting
GRC_PREFS_PATH
GRC_BLOCKS_PATH
HIER_BLOCKS_LIB_DIR
But my grc companion 3.7.6.1 keeps compiling the blocks to ~/.grc_g
> Aliasing on purpose?
Yes, it's called "bandpass sampling".

Sylvain
