Chaos-Based Satellite Digital Communication Systems

This proposal presents a hardware design to implement a next-generation secure digital communication system that uses chaotic signals. The use of chaotic signals in digital communication systems offers several advantages. First, the noise-like properties of chaotic signals prevent them from being easily detected, giving greater immunity from eavesdropping and interception. Second, an infinite number of chaotic waveforms can be generated, each with strong autocorrelation properties and weak cross-correlation properties. Third, chaotic signals possess the salient features of broadband communication systems such as multipath mitigation and resistance to jamming. The proposed Phase II effort aims to implement the simulated chaotic modulation/demodulation scheme developed during the Phase I to design a proof-of-concept prototype chaotic digital communication system.
