| 摘 要： | 本文就超昆沌通信问题，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－ｓｉｖｅ ｄｅｃｏｍｐｏｓｉｔｉｏｎ）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。

| Abstract: | A linear feedback method is proposed to design hyperchaotic communication system in this paper.The method can be considered as a general scheme to construct chaotic communication systems based on active-passive decomposition(APD)with fixed linear feedback structure.Two examples are offered to get a better understanding,one is based on 4D manifold piecewise linear circuit,the other is based on coupled map lattice.The numerical simulations agree very well with the analytical analysis,which demonstrates the efficiency of the method. |
