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: http://www.youtube.com/watch?v=Vn-dpUegUDQ 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! Balint http://wiki.spench.net/wiki/RF http://spench.net/ @spenchdotnet <http://twitter.com/spenchdotnet>
