Hello,
We are students of IIIT-Hyderbad, India, doing MS By Research and are
interested in participating GSoC-14 by building GRC gr-MIMO module.
We are from communication background and have fundamental knowledge of MIMO
and OFDM. Our main research area is to use MIMO technology along with
conce
Dear Sir,
Let me explain the reason of why to use the function:
set_min_noutput_items().
I am creating a custom interpolator block.
Says, the interpolation factor is 1000. Hence it is important to call
set_output_multiple(1000).
Meanwhile, for this block the interpolation factor depends on Samp
Dear all,
the OOT module gr-cdma that we have been working on with Zhe Feng is now
ready (also fully documented). You can find it here:

An important acknowledgement:
this project grew out of the DARPA SPECTRUM CHALLENGE:
our team eventually dropped out of
Thanks.

Hi everybody,
I just installed gr-lte with the Pybombs script. I get an error when I
launch the flowgraph with one of my record file.
Does anybody have a downlink file I could work with ?
Thanks

3.6.1 should have gr_modtool if I'm not totally mistaken; however, you'll have
a lot nicer and somewhat easier experience if you remove these ubuntu packages
and use pybombs to install a modern gnuradio 3.7 automatically from source:-)

Yes, sure.
Thank you.
Now it is working.

Try changing:
"digital.constellation_qpsk.base()"
to:
"digital.constellation_qpsk().base()"
Note the brackets after the constellation_qpsk constructor.

The WFM receive block includes deemphasis processing for improving the
sound of broadcast FM reception. This is going to screw up your APT
reception. You'll be better off making your own WFM demod block -- it's
just a quadrature demod followed by a low-pass filter.

Thank you.
Actually, I am doing it in the GRC interface.
When I use the .base(), it returns the following error:
*Param - Constellation Object(constellation):*
* Value "digital.constellation_qpsk.base()" cannot be evaluated:*
* 'function' object has no attribute 'base'*
I don't know what is the

Hi,
I'm trying to receive APT images from NOAA with a QHA antenna and I

and a resampler connected to the audio sink. I think that I should change

Hi,
The reason I signed up was that I saw a post (Google) on GNU Radio
regarding the RTLSDR dongles to which I wanted to respond. How do I
attach a post to a thread from the recent past for which I do not have the

Hi,
I just subscribed to GNURadio. I am getting each post as a seperate

On the signup sheet, I do not see a place to log in (with user/pswd) so
that things can be changed.
Thanks in advance.

My gnuradio flow graph has a custom block taking input from multiple

Hi all,
How to use file sink block in GRC. I want to extract output data from
rx_ofdm & tx_ofdm examples bolck in GNU radio to plot BER V/s EB/N0 in

opening anywhere. So please tell me what type of file we can get using f
gr_modtool looks for a known module structure.
If your module doesn't have that specific structure or keywords in its
CMakeLists.txt, maybe because it was not generated by gr_modtool, the build
system has been modified, it's for a different GNU Radio version etc.

Marcus
