摘要
提出了Rǒssler超混沌系统的同步方法,实现了Rǒssler超混沌系统的混沌同步保密通信,并利用线性稳定性理论,对接收系统设计了反馈控制器,使发射系统和接收系统达到混沌同步,保证了信号的精确复现,同时利用计算机仿真验证了本方法是可行的。
Synchronization of the hyperchaotic Rossler system was proposed to realize secure communication. Using the linear system stability theory, a feedback controller was designed for receiving system, and the chaotic synchronization between receiving system and transmitting system was achieved for that the transmitted signal is recovered with high quality. Simulation results show that this method is effective.
