Tom, its very interesting to see and learn your work on DSA. could you
forward this paper to us in the forum? i think the paper is not uploaded
yet. plus, its also great if I can try the code that you have done. is it
open to be download, tested and learned?

we also have a work on parallel sensing and transmit which will eliminate
the sensing time limitation and trade-off. we will published this in a very
near time =) ..

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 itself.
