The present contribution focuses on a parameter modulation type chaos communication system, using adaptive chaos synchronization. The proposed system is based on discrete-time additive nonlinear emitter and receiver systems. Modulating and recovered signals are quantized, aiming at a digital communication infrastructure. The proposed approach is more efficient than classical counterparts due to its...
In this paper, a new a secure communication scheme using chaotic signal for transmitting binary digital signals is proposed and which is then implemented on a Digital Signal Processor (DSP) board. The method uses the idea of indirect coupled synchronization for generating the same keystream in the transmitter and receiver side. This chaotic keystream is applied to encrypt the message signal before...
In this work, the synchronization of two indirectly coupled discrete-time chaotic systems is first demonstrated. Next, the result is then applied for presenting a secure communication system. The novelty of the proposed method lies on the generation of encryption key stream for discrete-time chaotic systems using indirect coupled synchronization. Simulation is performed for the proposed synchronization...
This paper presents a multiple-accessing chaotic digital communication system based on interleaved chaotic differential peaks keying (I-CDPK) modulation technique. The proposed communication system consists of four major modules: multiple-accessing chaotic transmitter (MACT), frequency modulation (FM) transmitter, FM receiver and multiple-accessing chaotic receiver (MACR). In this multiple-accessing...
