Dissipative Communications

Almost any communications system makes best use of scarce bandwidth by making the messages sent appear to be as random as possible. This is optimally done with spread-spectrum techniques based on Linear Feedback Shift Registers; this entails a significant amount of processing for a receiver to acquire and track a signal. We have found that simple physical systems can be designed that perform these functions through their dynamics, promising to make spread-spectrum communications significantly cheaper and faster.
