| Abstract: | A linear output feedback synchronization approach for chaotic Genesio system with application to secure communications is described.A sufficient condition of stable asymptotic synchronization and the boundary of feedback gain is given,based on the linear stability theorem.A computer simulation for secure communication is introduced,and it shows that the receiving and transmitting system can be synchronized quickly and the information can be recovered from the transmission signals with high quality. |
