| 摘 要： | 现有混沌跳频序列在混沌迭代次数、通信保密性和安全性等方面存在着不足.为解决上述问题,本文通过给出优化的Logistic映射函数,采用了一种改进的利用伪随机序列控制比特抽取来生成混沌跳频序列的方法.该方法各项跳频性能指标与已有研究成果相当,但其混沌迭代次数减少,序列安全性增强.

| Abstract: | In the current state-of-art chaotic frequency hopping schemes,there exist serious deficiencies in the iterative operation,the communication confidentiality and the security.To solve these problems,this paper presents an improved approach to generate chaotic frequency hopping sequences by using optimized Logistic map function and pseudo random sequence.With respect to frequency hopping,the approach achieves the same performance compared with existing methods.Thus,the method has low complexity in iterative op... |
