Summary: | This dissertation provides the conceptual development, modeling and simulation, physical
implementation, and measured hardware results for a practicable digital coherent chaotic
communication system. Such systems are highly desirable for robust communications due to
the maximal entropy signal characteristics that satisfy Shannon's ideal noise-like waveform
and provide optimal data transmission across a flat communications channel. At the core of
the coherent chaotic communications system is a fully digital chaotic circuit, providing an
efficiently controllable mechanism that overcomes the traditional bottleneck of chaotic circuit
state synchronization. The analytical, simulation, and hardware results yield a generalization of direct sequence spread spectrum waveforms, that can be further extended to create a new class of maximal entropy waveforms suitable for optimized channel performance, maximal entropy transmission of chaotically spread amplitude modulated data constellations, and
permission-based multiple access systems.
