Chaos in optimal communication waveforms [PDF]

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
The properties of nonlinear dynamics and chaos are shown to be fundamental to optimal communication signals subject to two practical and realistic design requirements: (i) operation in a noisy environment and (ii) simple hardware implementation. Starting with a simple electronic circuit, a linear filter receiver is presumed, and the matched optimal ...
