| Abstract: |
| The hyperchaotic synchronization was achived in the LC oscillator with only a one-dimensional drive signal via the active-passive decomposition method (APD) and demonstrated in theory.The potential applications in communications was further discussed in numerical experiments. The method provides the high encrypting efficiency and the signal can be recovered exactly. Moreover,The complete synchronization was realized in the hyperchaotic system combining the APD method and the adaptive method. This method robusts to the mismatched parameters. |
