摘要
通过对比利用混沌信号进行编码和解码调制的方式,说明了适合大强度信号的调制方式,提出了适合较大强度信号的混沌调制通讯方法.由于该方法允许较大幅度的信息信号,从而提高了通信的安全性.
By the comparative use of chaotic signal for encoding and decoding, this paper illuminates the modulation method for larger amplitude information signal, and proposes the chaotic modulation communication method for larger larger information signal. As the level of information signal can be equivalent to that of chaotic signal, the degree of security is strengthened.
