Frequency-Frequency Interactions in Chaos Communications

Abstract

In this research, the frequency-frequency interactions in chaotic systems hasbeen experimentally and numerically studied. We have injected two frequencies onchaotic system where one of these frequencies is modulated with chaotic waveformand the other is untiled as a scanning frequency to find modulating frequency. It isobserved that the Fast Fourier Transformation (FFT) peaks amplitude increasedwhen the value of the two frequencies are matched. Thus, the modulating frequencycould be observed, this leads to discover a new method to detect the modulatingfrequency without synchronization.
