摘　　要：基于1-D分段线性映射函数构造的混沌系统符号动力学,该文研究了一种能直接对混沌符号序列进行加、减及乘法运算的方法。由两串符号序列之间的轨道距离定义推导并证明了相应的运算法则。通过FIR数字滤波器卷积和操作的计算机数值仿真表明,采用这些方法运算得到的结果与传统二进制算术编码算法完全等效,可应用于混沌信号处理系统。Based on symbol dynamics in 1-D piecewise linear mapping chaotic systems, an arithmetic method processing chaotic signals is studied in the paper, including addition, subtraction and multiplication. The operational rules are calculated and proved according to a definition of the distance between two chaotic sequences. By computer simulation with convolution sum of FIR digital filter, the results show that the model is the same as traditional binary coding arithmetic, which can be used in chaotic signal processing systems.
