保密通信中稳健差拍同步方法的描述与验证

Robust dead-beat synchronization of discrete chaotic systems and application to secure communications

结合自适应信道盲均衡和离散混沌系统的稳健差拍同步提出了一种存在信道畸变时的离散混沌系统的稳健差拍同步方法。该方法把混沌误差同步作为能量函数,利用进化算法训练递归神经网络完成自适应信道盲均衡,均衡器的输出作为混沌接收器的激励信号,从而在完成信道盲均衡的同时混沌系统达到同步状态。此外,提出了一种利用离散混沌系统稳健差拍同步实现存在信道畸变时的保密通信的方法。

A robust dead-beat synchronization method was presented for discrete chaotic systems using adaptive channel blind equalization and dead-beat chaotic synchronization. This method utilizes chaotic synchronization error as the energy function and evolutionary programming to train the RNN, whose output was used as the driving signal for the chaotic receiver. Furthermore, based on the robust dead-beat synchronization method, a new secure communication method was proposed.
