Forum: GNU Radio Paper: DCSK chaotic modulations with GNU Radio.

Hi,

  I would like to announce a paper I published few months ago with
some friends on a DCSK chaotic modulation implementation with GNU
Radio.  The full reference is:

Georges Kaddoum, Julien Olivain, Guillaume Beaufort Samson, Pascal
Giard, Francois Gagnon: "Implementation of a Differential Chaos Shift
Keying Communication system in GNU Radio," International Symposium on
Wireless Communication Systems (ISWCS), August, 2012.

  I took the opportunity to add a copy on the AcademicPapers page of
the wiki:

http://gnuradio.org/redmine/projects/gnuradio/wiki...

  The code of the modulator and demodulator used in the paper is
available at:

https://github.com/jolivain/gr-chaos

  Feedback and comments are welcome.  If somebody thinks this has a
place in the main repo, let me know what remain to be done.

  Regards,

-- Julien Olivain.

Thanks for adding this! I had a quick peak, and it seems quite
interesting what you've done.

Perhaps you could add a link and a very brief description on CGRAN
(https://www.cgran.org). This is where people would most likely look for
extensions like this. You don't have to upload code to the CGRAN SVN
repos to do this.

Cheers,

Out of curiosity, how were you able to determine Eb/N0 in Fig. 3? Could
you use the SNR measurement blocks in GNU Radio?

  Hi Martin,

  Basically, we measured everything "by hand", using the standard
block in GNU Radio 3.5 (plus some modifications in the "simple
framer").  So, no, we didn't use the SNR estimation blocks in GNU
Radio (if I remember well, these blocks were not merged in GNU Radio
when we did these experiments, last year).  We had the setup described
in section 5 of the paper (2 usrp, a noise generator with a mixer).
For each point of the graph, we measured the noise power alone, the
signal power alone, then the bit error rate when mixing the noise and
the signal.  With some matlab code we converted the SNR to Eb/N0 to
generate the Fig 3 (instead of using a SNR estimation technique).  We
did this because we wanted to actually measure the total performance
loss of the whole transmission system (modulation, implementation,
sync. recovery, usrp) and compare the results with the theoretical
limits.  Moreover, I have no idea how far is a usrp transmit channel
from a pure theoretical AWGN one.

  Other things that would be nice to test would be to compare this
"hand made" SNR measures with SNR estimation techniques, both in a lab
setup and in a real-world outdoor environment.

Hello,

I wonder how I can add a paper to the list of academic papers (
http://gnuradio.org/redmine/projects/gnuradio/wiki...). I 
can
see the listing of all papers but I don't see a link where I can add my 
own
paper.

I am sorry if the question seems too basic :S. Any feedback will be
appreciated.

Thanks,

Nazmul

Martin,

Thanks a lot for your feedback. I have created an account on this page. 
My
login name is: nazmul.islam. Can you please add me as a contributor? I
would like to add my two GNUradio based papers to the mailing list.

Thanks,

Nazmul

Should work now. Thanks for sharing and keeping the wiki up to date.
