| 摘 要： | 通过混沌光通信系统模型的建立，利用MATLAB对Logistic混沌方程产生混沌序列进行频谱能量和功率谱密度分析，发现混沌信号的频谱密度可以作为光通信系统模型的检测依据，并在此基础上进行MATLAB仿真研究，表明可以将混沌信号作为信息载体，实现光通信的混沌传输，由于混沌理论具有良好检测微弱信号的能力，从而开辟了光通信长距离无色散传输的另一种途径．

| Abstract: | Based on the model of chaotic optical communication system,Logistic chaotic sequence spectrum power and the power spectral density are analysed by using MATLAB,discovering that the power spectral density of chaos signal can provide testing basis for optical communication system model,then MATLAB simulation is conducted on this basis.The result indicates that the chaos signal can be used as information carrier to achieve the chaos transmission of the optical communication.Since it has an excellent ability to... |
