摘要
利用简单的非线性方程能产生具有噪声特性的混沌信号,基于嵌入Matlab计算模块的LabVIEW平台设计了一系列混沌信号发生及辨识仪,包括Logistic、Duffing和Lorenz3种典型的混沌系统。该系列虚拟仪器能够产生具有实用价值的白噪声信号,用于通信保密等场合,又可将采集到的信号进行功率谱或相关平面分析而有效地区分混沌和噪声。
Chaotic signal with noise properties can be generated by a simple nonlinear equation. A series of chaotic generators and identification instruments were designed based on LabVIEW and computation module of Matlab. These virtual instruments (VI) included three typical chaotic systems, such as Logistic, Duffing and Lorenz. By using these VI, practical white noise signal can be generated, and chaotic signal and noise signal can be identified with the method of power spectrum and correlation plan.
