Abstract
A plan is presented to demonstrate the feasibility and practicality of a radio-frequency Hayes-Corron (H-C) chaos-based communication system employing an optimal spread-spectrum chaotic communication theory to achieve superior low-power, low-probability of interception, multiple-user access, and portability goals. By integrating three concepts: 1) chaotic spreading sequence generation, 2) Hayes encoding, and 3) Corron matched filtering, the richness of chaotic system behavior is harnessed in the key transformational processes of the communications scheme. Chaotic spreading sequences have previously been demonstrated in published research to provide security benefits. Hayes encoding is an efficient method by which information can be encoded on a chaotic waveform using arbitrarily low-power modulation so that a symbol can be encoded on nearly every carrier oscillation. Corron matched filtering is a cutting-edge extension of standard linear matched filter theory to chaotic waveforms permitting their optimal detection. At low frequencies the H-C concept has been demonstrated using low-power COTS components. Under this effort a RF H-C design study will be conducted. A Matlab simulation of a digital audio H-C system will be built and detailed model development undertaken using PSPICE and other tools. A prototype oscillator and matched filter will be fabricated and tested/evaluated for controllability, reliability, and performance.
