Generalized synchronization of unified chaotic system and the research of CSK

Unified chaotic system is a newly-suggested chaotic system. By means of generalized synchronization (GS), the synchronized control of unified system is studied. For unified system has good properties of auto-correlation and cross-correlation, it takes advantage of chaotic shift keying (CSK) scheme to make experiments. In this paper, the approach of GS control has been presented. Then the entire scheme of CSK based on unified chaotic system has been detailed. Finally the results of numerical simulations prove the effectiveness about GS of unified chaotic system. The approach is suitable for the research situation with parameter mismatch and channel distortion.
