摘    要:提出了一种基于细胞神经网络和混沌交错反馈产生扩频序列的设计方法,用计算机仿真对该混沌扩频序列的平衡特性、游程特性、位移特性、相关特性和线性复杂度等伪随机特性进行了系统的分析,并分析了该序列的奇/偶相关特性.结果表明,该混沌扩频序列具有理想的伪随机特性,可以作为扩频通信中的扩频码,同时系统的交错加强了通信的保密性.

关 键 词:细胞神经网络  混沌  奇/偶相关特性  扩频

Abstract:Based on cross-feedback of chaos and CNN,a method generating spread-spectrum sequences is proposed in the paper.By using computer simulation,the properties of the spread spectrum pseudonoise sequences,such as balance property,runs property,shift property,correlation property,are analyzed.The simulation results indicate that the chaotic spread spectrum sequences have ideal pseudonoise properties and can be applied in spread spectrum communication system,while the security of communication system is greatly e...
Keywords:CNN  Chaos  Even and odd correlations  Spread Spectrum
