OHM2013: Hacking the radio spectrum with GNURadio

in RF, SDR, Videos by the machinegeek | 2 comments


At the OHM2013 conference held last summer outside Amsterdam, J. M. Friedt discussed his use of GNURadio as a signal processing prototyping tool. He writes, “We demonstrate the use of this software environment for implementing new digial communication mode decoding algorithms, qualifying low frequency circuits by using the audio card as a network analyzer, all the way to developing a FMCW RADAR.

We will demonstrate how a given 25-euro hardware allows for receiving analog communication signals (commercial FM), digital modes (radiomodem and ACARS communication protocol between planes and airports), and with a bit more understanding the implementation of a continuous wave RADAR as originally demonstrated at MIT using dedicated hardware, and even weather satellite images broadcasted from Low Earth Orbiting (LEO) satellites, as was demonstrated with dedicated hardware a few years ago at WTH.”

The basics of this presentation are available as a 31 page PDF.

Notice that Sylvain Munault and Harald Welte mentioned a mistake in my statement: although the Elonics E4000 is no longer available, osmosdr will keep on running with all the other DVB-T chips and most significantly the R820T.
