Imagine noise radiator capable of making your spectrum analyzer
look like /dev/urandom across the board. There's no center frequency,
no clock, no freq hopping, no spreading, no observables, no off the
shelf wireless hardware or reference design... it's not based on that.
To any viewer, it's just background noise. To you and your peers
who hold, say, a shared XOR key for data and a seed for DRBG noise,
it looks like data... lots of data ;-) With achievable datarate,
error correction, and unjammability governed by the range of spectrum
you can generate noise over. You could even mimic within existing
spectra if need be. And its nature is highly reistant to location.
The amplifiers and radiators to cover the spectrum are hardware.
Everything else is SDR.

There is at least one good paper on this, particularly involving
GNURadio style SDR as the enabling basis, but I forgot the magic
search terms to find it again.

While not the paper in mind (and not necessarily from the new SDR
guerrilla / cypherpunk / darknet radio crowd), these are somewhat

Digital Chaotic Communications

Synchronization in Cognitive Overlay Systems

Covert Ultrawideband Random Noise papers by Jack Chuang and Ram Narayanan...

Can you link to some better docs, whether philosophy, theory or
application, using SDR along the main topic above? Thanks.
