摘要 采用DSP Builder开发工具,利用混沌信号实现对通信数字信号的加密与解密。首先在Simulink中建立系统通信模型,采用FM对混沌信号进行差分键控形成FM-DCSK信号,然后用数字信号控制FM-DCSK信号,形成调制信号,并在接收端进行信号恢复,然后进行仿真,生成硬件描述语言下载到系统板,实现混沌保密通信。 It encrypts and decrypts to communication digital signals based on chaotic signal by the DSP Builder in this article. Firstly, it needs to build a system model of communication in Simulink through the DSP Builder. In order to get FM-DCSK signal, it needs to achieve DCSK to chaotic signal by FM. Then FM-DCSK signal is controlled by digital signal and it can get modulation signal, and the signal recovers on the receiving side, then runs the model in simulator, creates hardware description language, and it is downloaded in system board. Finally, it realizes chaos secret communication.
