【摘要】 在已建立的数字流混沌产生器的时钟间隔脉冲驱动同步原理和实现方法的基础上,为解决该方法存在的通信双方程序不一致所导致的噪声随时间增加而增加的问题,提出了模型参考同步去噪法,旨在减少同步噪声,以获得好的信噪比.实验结果表明该方法有效地降低了噪声.更多还原

【Abstract】 Based on the theorem of synchronization of digital-flow chaos in secure communications, a scheme of secure speech communication was presented and realized, a method using model references was given to solve the problem that noise will be increased with time going because of programming variance both communication sides. Reducing synchronic noise and promoting the ratio of signal power and noise power are made with the method. The experimental results show it will reduce noise efficiently.更多还原
