摘要
为克服用硬件电路实现复杂混沌映射的困难问题,基于MATLAB/Simulink建立多涡卷混沌映射的数值模型,采用快速原型技术通过输入/输出卡,将虚拟仿真信号转化生成实际的物理电信号,并与实际硬件电路连接起来,构成混沌通信系统的半实物仿真模型。对模型的实验结果分析表明,数字仿真模型生成信号不仅具有优良的统计特性,而且通过模拟输出卡输出的实际电信号和信号源数字仿真模型生成的信号一致。
We constructed a digital simulation model of multi-scroll chaotic map using MATALAB/Simulink in order to implement the chaotic generator. This scheme could ease the difficulties of the hardware circuit implementation of complicated chaotic map. Using Rapid Prototyping technologies, we transformed the virtual simulation signal into physical electrical signal through Input/Output devices. In the given experiments, not only can the generated chaotic signal have excellent statistics properties, but also real time electrical signal can agree well with that generated by the digital simulation model.
