摘要
提出符号动力学意义上的混沌同步概念,扼要阐明与数值意义之间的关系,并研究一特定耦合离散动力系统的混沌同步特性,数值实验表明该耦合系统能达符号意义上稳定的混沌同步,用符号序列表征混沌同步过程更直观,符号意义上的混沌同步更容易实现、有较强的抗噪能力。
We propose the chaotic synchronization in symbol dynamical meaning and simply elucidate the relation to numerical meaning. The chaotic synchronization of a special coupled discrete dynamical system is studied. Numerical simulations show that the stable chaos synchronization can be realized in the system. Using symbol sequence to present and judge the synchronized proceed is more perceivable. This kind of chaotic synchronization can be realized easily and it is strong to anti-noise.
