GNU Radio: Hacking the RF Spectrum with Free Software and Hardware
Matt Ettus, GNURadio
Eric Blossom, Blossom Research

Track: Untethered
Date: Wednesday, April 23
Time: 2:00pm - 2:45pm
Location: Stevens Creek

GNU Radio was launched in April of 2001 to build a platform to learn about, explore, and deploy open source software-defined radios. "Regulatory hacking" has led to the creation of a software HDTV transmitter and receiver. The HDTV receiver can serve as the basis for an open source digital TV recorder in the TiVo/Replay genre.

We'll demonstrate some applications that we've built with GNU Radio including:

  • Concurrent multi-channel FM receiver,
  • The mother of all scanners,
  • Our all software ATSC (HDTV) receiver.
  • If it's working by the conference, we'll also demo our encrypted digital radio transceivers.

We'll include a show and tell of radio construction by scripting together signal processing modules (radio hacking made easy), transparent use of SMP hardware, and other cool stuff.
