Hi all, I just wanted to thank the GnuRadio community for such a great
effort. I recently gave a talk at the American Physical Society
(Division
of Fluid Dynamics) in which I presented results on a new flow-velocity
sensor I’m developing that produces an AM waveform. Until recently I’ve
been using standard data acquisition techniques with an 8-bit Lecroy DSO
to capture the signal and perform demodulation in post-processing.
However, just before the conference, I successfully integrated GnuRadio
and the USRP into the experiment, and boy what a difference those 12-bit
digitizers make to demodulate the signal! Not to mention the real-time
processing. Plus I demonstrated wireless transmission from the sensor,
which is a real coup.
I brought a working demo to the conference, with the USRP, and
demonstrated the device working in real-time. I can say it was a big
hit,
particularly the gui showing the real-time demodulation. That really
added some kick to the presentation.
Anyway, the paper I presented is at
www.nd.edu/~ematlis/Papers/Plasma_probe/JANNAF_2006_matlis.pdf
Thanks again!
