First Experimental Solution for Channel Noise Sensibility in Digital Chaotic Communications
TL;DR: The proposed solution to the high channel noise sensibility problem of digital chaotic communications by avoiding disruption of the slave/receiver dynamics by injecting the driving signal is tested and validated through experimental realization of a wireless hyperchaotic communication system based on ZigBee communication protocol.

On the Performance of a Digital Chaos-Based Communication System in Noisy Channels
Greta A. Abib,Marcio Eisencraft +1 more
TL;DR: This work evaluates the performance in terms of Bit Error Rate (BER) of a binary communication system, based on chaotic synchronization, when white gaussian noise is added to the transmitted signal and proposes an encoding function that allows controlling the trade-off between how apparent is the message in the transmitted chaotic signal and BER performance.

Synchronization in chaotic systems
TL;DR: This chapter describes the linking of two chaotic systems with a common signal or signals and highlights that when the signs of the Lyapunov exponents for the subsystems are all negative the systems are synchronized.
Book
Nonlinear dynamics and Chaos
TL;DR: The logistic map, a canonical one-dimensional system exhibiting surprisingly complex and aperiodic behavior, is modeled as a function of its chaotic parameter, and the progression through period-doubling bifurcations to the onset of chaos is considered.

Synchronizing chaotic circuits
TL;DR: The authors describe the conditions necessary for synchronizing a subsystem of one chaotic system with a separate chaotic system by sending a signal from the chaotic system to the subsystem by sending signals from the Chaos Junction.
