Tent混沌伪随机序列发生器设计与实现

The Design and Realization of Tent Pseudo-random Sequence Generator

混沌理论作为非线性科学是近年来发展最快的分支,具有非周期、连续宽频带、类噪声和长期不可预测等特点。Tent映射具有迭代方程简单,易于实现,数量众多,相关性能良好等特点。本文设计了Tent映射的二值量化序列算法,将Tent实值序列转化为二进制序列,生成了Tent伪随机序列。使用可视化仿真工具Simulink对该序列发生器进行了数值仿真,证明了方案的正确性和可行性。

As the most rapid development of Nonlinear Science in recent years,Chaos theory has the characteristics of non periodic,continuous broadband,class noise and long term unpredictable. Tent mapping has the characteristics of simple iterative equation,easy implementation,large quantity,good correlation and so on. In this paper,the binary quantization algorithm of Tent mapping is proposed,the Tent real valued sequence is converted to binary sequence by using the above algorithm,and the Tent pseudo-random sequence is generated. Moreover,the numerical simulation experiments of the system are carried out using the visual simulation tool Simulink software,so the correctness and feasibility of the scheme are proved.
