Hello Adib,

CROSS was the product of Tim Newman and myself, and was created a couple of years ago.  Development stopped some time ago, and the documentation is wildly out-of-date, but the code is still freely available: http://www.cornet.wireless.vt.edu/trac/wiki/Cross

CROSS does provide a _skeleton_ cognitive engine, and a framework to wrap it in, but it does not provide a working cognitive engine out-of-the-box.  The goal of the project was to develop something we could sit on top of any SDR platform - GNURadio, OSSIE, whatever, and establish a distributed waveform.

I've actually never looked at Tom's work, so I can't comment on the similarities.  It may be very similar.  My understanding, and Tom can correct me if I'm wrong, was that Tom's dissertation focused mostly on the CE component itself.  CROSS is algorithm and CE agnostic; it cares only about how the components talk to each other.

Glad to hear you found it useful enough to cite, and I hope this helps!

No, I'm afraid I can't help you there. This was from when I was working on
my Ph.D. years ago at Virginia Tech and I no longer have access to the code.
Any papers I have can be found in IEEE Xplore or from the SDR Forum (now
Wireless Innovation Forum). I was also mostly interested in the development
of a cognitive engine that I applied to the DSA problem, not really DSA


oh its too bad we cannot see the code. I follow some of your work on
cognitive engine when you are with VT during my literature of my master, it
was a nice work your team done in VT with CR.

Last time there was a colleague in this forum introduce me to the CROSS
which done by VT (i also cite this in my thesis) ..and inside the CROSS
there is a cognitive engine. is this your work? =)

thanks tom.


While CROSS isn't my code, the general design of the cognitive engine is very much like what I set up in my work and dissertation, so I'm assuming it's largely based off it.
