摘要：

提出一种基于改进的Logistic+Tent映射的短波差分跳频转移函数算法。利用该算法构造跳频序列,针对跳频图案进行数值仿真并与原映射进行比较。仿真结果和性能分析表明,该新算法所构造的跳频序列不仅具有更好的随机性、平衡性,均匀性和相关性,符合跳频码的要求,而且具有较高的线性复杂度,因此,基于改进的Logistic+Tent混沌映射构造的跳频序列,具有较强的抗干扰能力和安全保密性。

关键词: 差分跳频序列, 混沌映射, 跳频序列

Abstract:

This paper proposes a new shortwave DHF transfer function algorithm which depends on advanced Logistic plus Tent map.The frequency Hopping code is constructed by this algorithm and the Hopping pattern is numerically simulated and compared with the original mapping.The result demonstrates that it has better randomness,uniformity,balance,and a fairly large linear complexity.The frequency hopping code based on advanced logistic and tent map has a good anti-interference performance and security confidentiality.

Key words: difference frequency hopping;chaotic map;frequency hopping sequences
