IEEE 802.11 a/g/p receiver

GNU Radio
1

Hello all,

I’m currently working on an IEEE 802.11 a/g/p receiver and I think that
meanwhile it has reached a state where others might be interested. With
my desktop PC I can decode 20MHz bandwidth signals without any under
runs.

I tested it with quite a lot of 11a devices and also with 11p
prototypes.

Currently, it lacks a good algorithm for channel estimation and is thus
limited to BSPK and QPSK.

If you are interested you can find some more information on our website:

Best,

Bastian

This is good example of using stream tags and async messaging in a
flowgraph. Nice work!

Hi Bastian,

this is nice stuff! I see you have a publication on the module, would
you mind adding it to our wiki page on papers,
http://gnuradio.org/redmine/projects/gnuradio/wiki/AcademicPapers ?

Cheers,
MB

I was fiddling around with the wiki today, and added it myself.
It’s pretty good, and I can recommend it for reading-- it gives a great
overview over the module, but also some of the GNU Radio concepts.

As usual, I would like to encourage researchers to add their papers to
our “Academic Papers” section if you have published anything related to
GNU Radio.

There is quite a nice collection of GNU Radio and SDR papers and related
links accumulating on this page! This is great for both GNU Radio, and
SDR in general.

I see that some links are out of date now and no long available.
Although it’s good to have them as general references (which one can
probably find via a quick internet search), it would be even better if
they worked from this page. Hence, if you and/or your group has entries
on this page, I encourage you to check them every so often and keep them
up to date (now is as good as time as any :).

A number of entries are using the following format, which I just used
for the UND entries I just added:

{{{
h4 Your School Name

“Your School Name”:http-link-to-your-school
“Your Department”:http-link-to-department

  • Author(s), ““Title”:http-link-to-document”, specific info including
    publication year.
    }}}

and then repeat “* Author(s)…” as needed; and/or add more departments,
your business name, and so forth. If you want to link in your specific
WWW area to your name, feel free to do so.

I would encourage folks to use the above formatting, since it provides
all of the information necessary to both have the entry look nice as
well as work correctly. I also encourage you to “Preview” your changes
before committing them, to make sure they look nice as well as work
correctly no matter what formatting you choose to use.

All of the above said, just getting the entries into this page is more
important than formatting. As I stated already, if the entry is there
one can, with a high rate of success, do an internet search to find the
document.

Keep up the great work, and remember to link it in! - MLD

Thanks for your comment and for adding it!
I just created an account on gnuradio.org and will see if I can
contribute something to the Wiki.

Thanks Michael for tidying up the Academic Papers page. I like the
format
since it allows quick identification of the papers from each
institution,
which tend to be related.

Best regards,
Carles

I have installed the code, but only receive a sequence of “0” and the
crc is
wrong. Did you guys try this code and explain why?
