摘要:
为了解决传统通信方式本身不具有隐匿信息能力的问题,本文采用FPGA设计了一个基于Duffing振子阵列的四进制混沌接收机,主要用于接收混沌Duffing振子产生的四进制混沌信号。进行信号调制时主要利用了混沌Duffing振子的时域信号具有隐蔽性和类噪声的特性构建了较为安全的通信信息;解调时,利用了Duffing振子阵列对信号的幅度敏感性,屏蔽了其相位敏感性,使其可以解调具有任意相位的混沌信号。实验结果证明该混沌接收机能正确接收具有任意相位的混沌信号,保密性能好。
Abstract:
In order to solve the problem that the traditional communication mode itself does not have the ability to hide information, FPGA is used this paper to design a quaternary chaotic receiver based on Duffing oscillators array. It is mainly used to receive quaternary chaotic signals generated by Duffing oscillators. Relatively safe communication information is constructed by mainly utilizing the concealment and noise-like characteristics that the time domain signal of chaotic Duffing oscillators have during signal modulation; during demodulation, the amplitude sensitivity of Duffing oscillators array to signal is utilized and its phase sensitivity to signal is shielded, so that it can demodulate chaotic signal with arbitrary phases. The experimental results show that the chaotic receiver can correctly receive chaotic signals with arbitrary phase and has good security performance.
