摘要
研究了具有连续时延双神经元系统的双向耦合混沌同步问题及在扩展频谱保密通信中的应用。利用Krasovskii-Lyapunov理论,给出了系统同步的一个充分条件,通过选择合适的耦合参数可以保证全局混沌同步。给出了使用混沌掩码技术在扩展频谱保密通信中的应用实例。
The chaotic synchronization between two time delayed neuron chaotic systems with linearly bi-directional coupling and to its application of spread spectrum secure communications are studied.Some generic criterion is developed for choosing the appropriate coupling parameters to ensure global chaotic synchronization based on Krasovskii-Lyapunov theory.FinaUy, an application example is given, which uses the proposed chaotic system to realize spread spectrum secure communications based on the chaotic masking strategy.
