In chaos secure communication system, to separate effectively chaos and harmonic signal is an important way of testing systematic confidential performance. In recent years, the time-frequency analysis theory is more and more mature, effective time-frequency analytical algorithms are emerging constantly. The paper starts with the time-frequency character analysis of the chaos, the noise and the harmonic...
The separation of chaos and signal is an important problem of chaos signal processing. In recent years, the time-frequency analysis method is more and more mature. This paper starts with the time-frequency character analysis of the chaotic signal, the noise and the harmonic signal. It also discusses the influence of the amplitude, frequency of harmonic signal and the signals to noise ratio (SNR) on...
