摘要: 将一个三维自治系统作为网络节点, 研究以该混沌系统为节点的全局耦合网络渐近同步问题. 用混沌掩盖的方法将其应用于保密通信中, 通过加入Gauss白噪声对系统进行干扰, 并用小波分析理论对信号进行去噪处理. 数值仿真结果表明, 经小波阈值去噪后, 可无失真地恢复有用信号.

Abstract: Using a threedimensional autonomous system as the node, we studied the asymptotic synchronization of globally coupled network with the chaotic system as the node, and used chaos concealment method to apply it to secure communication. By adding Gaussian white noise to interfere with the system, we used wavelet analysis theory to denoise the signal. The results of numerical simulation show that the signal can be recovered without distortion after the wavelet threshold de-noising.

Key words: wavelet denoising, chaos synchronization, complex network, secure communication
