A Kind of Shortwave Frequency Hopping Code Based on DFH Transform Function
-
摘要: 该文提出了一种基于Logistic映射的短波差分跳频转移函数算法,利用该算法构造跳频图案,并对跳频图案进行了数值仿真和性能检验。研究结果表明:该算法所产生的跳频图案不仅具有较好的随机性、均匀性、平衡性和相关特性,符合短波跳频图案要求,而且,具有大的线性复杂度,因此,基于混沌映射构造的短波跳频序列具有较强的抗干扰能力和安全保密性。

Abstract: A new shortwave frequency hopping codes based on difference frequency hopping transform function which depended on logistic map is presented. The performance of the frequency hopping codes is researched .The results indicate that it has better randomicity, uniformity, balance, and higher privacy because of the character of chaos. -
