Abstract
This paper describes a technique for transmitting information using a RF chaotic modulation–demodulation system. This system is composed of two parts: (i) a modulation–demodulation circuit, which is constructed using a chaotic Colpitts oscillator and (ii) an interface circuit, which is constructed using wideband OP and passive elements. The information is masked by adding a RF chaotic signal to be transmitted, and is obtained by subtraction of the chaotic signal at the receiver. The results of both practical experiments and simulations are presented to verify our approach. © 2005 Wiley Periodicals, Inc.

A full analysis of a chaotic microwave oscillator based on envelope transient analysis is presented for the first time. The technique overcomes problems encountered by time domain and harmonic balance methods to simulate such kinds of circuits. A bifurcation diagram of the oscillator is obtained. Th
We numerically investigated the dependence of the decryption characteristics in a message modulation type chaos secure communication system using optical fiber ring resonators (OFRRs) on the coherence condition of carrier light. Since the output dynamics of OFRRs were formed on the basis of interfer
