[Discuss-gnuradio] GRC 3.6 / 802.11 a/g test signal

[Ernest Szczepaniak]

Greetings engi's!

I'm currently working on my masters (802.11 wlan receiver with
MATLAB/USRPN210). After creating all the important stuff ie:

-symbol finder
-time synchronization
-coarse and fine frequency compensation
-symbol demodulator
-deinterleaver
-Viterbi decoder
-descrambler etc.
-MAC layer decoding

i'm looking for any tested 802.11 a/g IQ signal for further research
becouse live samples captured by USRP seem to have incorrect result's
(wrong frame type MAC field, random MAC adress, CRC, parity bits etc).

And here comes my 1st question.

Is there any place where i can get some real, tested IQ wlan signal i
a/g standard and full description (rate, coded data, adresses, included
MAC fields)? Tried with Agilent Signal Studio but files are saved in
.wfm encrypted format :(

I also found GRC beacon frames transmitter, written in GRC

http://rrsg.ee.uct.ac.za/members/jwamicha/gr-wlan.tar.gz

but due to having GRC 3.7 (where 'gnuradio-core' was repleaced with
'gnurdaio-runtime') i can't simply compile this file becouse of an
error:

---------------------------------------------------------------------------

checking for GNURADIO_CORE... configure: error: Package requirements
(gnuradio-core >= 3) were not met:

No package 'gnuradio-core' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables
GNURADIO_CORE_CFLAGS
and GNURADIO_CORE_LIBS to avoid the need to call pkg-config.

---------------------------------------------------------------------------
It seems that those binaries arent compatible with my GRC version :(

Any helpful guy to install this library and send me IQ signal of this
beacon frame? (in any MATLAB readable format - simple file sink in GRC).

Looking forward for any reply.

Thanks
