跳频技术具有抗干扰、抗截获、频带共享和码分多址等优点,在民用移动通信、军事无线电通信、现代雷达和声纳等电子系统中具有广泛的应用.寻找和设计最优跳频序列族是研究跳频通信技术的重要议题,因为跳频序列是跳频系统中不可或缺的重要组成部分.本文基于交织技术和中国剩余定理,构造了两类新的跳频序列族,导出了新序列族的各类汉明相关性质.研究结果表明,通过选择恰当的参数和已知跳频序列族,本文所提方法可递归得到大量的最优跳频序列族.
Frequency-hopping spread spectrum (FHSS) systems, which have the properties of anti-jamming, anti-intercept, channel sharing and code division multiple access, have been widely applied to mobile communication, military radio communication, modern radar and sonar echo-location systems. An important subject in frequency-hopping (FH) multiple-access systems is to find optimal frequency-hopping sequence (FHS) sets, which are an indispensable part of FHSS systems. Based on the interleaving technique and the Chinese reminder theorem, two classes of FHS sets are constructed and the Hamming correlations of the new FHS sets are derived. The results show that a large number of optimal FHS sets can be obtained recursively by choosing appropriate parameters and specific FHS sets.
