چکیده

We demonstrate here a new dual receiver synchronization scheme that works because we are able to store samples over an entire bit period and then perform an intelligent comparison by methods we introduce. We discuss advantages for message camouflage of transmissions near the noise floor. Our results show better bit error probability performance in comparison to previously published methods. This represents a significantly different and promising new way to use chaotic transmitters to advantageously transmit designed signals.

Modified Sliding-Mode Control Method for Synchronization a Class of Chaotic Fractional-Order Systems with Application in Encryption

In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...

A Chaos-Based Communication Scheme Using Proportional and Proportional-Integral Observers

In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator. We use a combination of the addition and inclusion methods to mask the information. The performance of two observers, the proportional observer (P-observer) and the proportional integra...

Dual combination combination multi switching synchronization of eight chaotic systems

In this paper, a novel scheme for synchronizing four drive and four response systems is proposed by the authors. The idea of multi switching and dual combination synchronization is extended to dual combination-combination multi switching synchronization involving eight chaotic systems and is a first of its kind. Due to the multiple combination of chaotic systems and multi switching the resultan...
