Noise Locked Loop

We are building a nonlinear dynamic system that constitutes a new kind of phase-locked loop. This Noise Locked Loop (NLL) will entrain with an incoming pseudo-random bit stream generated by a matched LFSR, instead of simple sinusoidal signals. The hope is that this will be a cheap and very effective front-end for spread-spectrum receivers, allowing spread-spectrum to be deployed for new applications. For example, one could potentially use spread-spectrum clock distribution on large chips. In the process, we have begun to understand how to compute using nonlinear dynamic systems.
