本文就超混沌通信问题 ,提出了一种超混沌保密通信系统的线性反馈设计方法 ,并阐明它是一种APD(active- pas sivedecomposition)同步系统的构造方法。这种设计方法的优点在于采用了固定的线性反馈结构 ,而与原始系统的形式无关。我们分别给出了两个例子 ,一个是基于4维流形分段线性超混沌电路的连续系统 ,一个是基于耦合映象格子的离散系统。解析分析和模拟结果都证明了这种方法的有效性
In this paper, a method of linear feedback design for hyperchaotic secure communication is proposed, and a method of constructing an active-pas sivedecomposition (APD) synchronous system is proposed. The advantage of this design approach is the use of a fixed linear feedback structure, regardless of the form of the original system. We give two examples respectively. One is a continuous system based on a 4-dimensional manifold-piecewise linear hyperchaotic circuit and the other is a discrete system based on a coupled map grid. Analytical and simulation results prove the effectiveness of this method
