Hi folks,
For Ruxcon 2011 http://www.ruxcon.org.au/ I gave a presentation
<http://www.ruxcon.org.au/2011-talks/an-introduction-to-software-defined-rad
io> at the weekend covering some of the neat things you can do with
SDR. In
particular, I spoke about some of my recent projects that employ GNU
Radio:
tracking aircraft using Mode S/ADS-B
http://spench.net/drupal/research/mode-s in order to visualise your
local
airspace in web-streaming 3D, and creating a satellite communications
demodulator using blind signal analysis.
I’ve uploaded a video of the talk and would like to share it with you:
If you wish to skip to a specific section, just open the description
pane on
the video’s page and jump to a time in the topic list.
During the course of these projects, I added and modified a number of
GR/GRC
blocks. In the coming days, I will consolidate the modifications to the
GR
source tree into a patch, and put ‘gr-baz’ on GitHub. The gr-baz package
contains several new blocks, GRC block defs and Python scripts, e.g. for
sat
comms (automatic FEC parameter search, convolutional code
(de-)puncturing,
symbol swapping, raise-to-power, variable delay, text-file-dumper) and a
seamless BorIP http://wiki.spench.net/wiki/BorIP sample source
drop-in
for the USRP 1 and FUNcube Dongle to allow remote streaming and control
over
one’s LAN. I shall post the relevant info when it’s all up.
All comments are welcome!
