| Abstract: | 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.Finally, an application example is given, which uses the proposed chaotic system to realize spread spectrum secure communications based on the chaotic masking strategy. |
