| 摘 要： | 针对差分跳频系统频率编码及跳频序列的设计问题,提出利用混沌映射构造差分频率编码,并分析了其频率状态转移的Markov性和编译码特点。最后检验了基于混沌映射的差分跳频频率编码的统计性能,结果表明,其产生的跳频序列具有较好的均匀性和随机性,不失为一种具有较高线性复杂度的有效的差分跳频转移函数。

| Abstract: | In order to design frequency encode and frequency hopping(FH) sequence in
differential frequency hopping(DFH) system, a differential frequency encode bas
ed on chaos mapping is provided, and Markov character of frequency state transf
er in frequency encode is analyzed. The statistical results show that the frequ
ency hopping sequences driven by chaos differential frequency encode have bette
r uniformity and randomness, which is effective to construct DFH transfer functi
on with higher linear complexity. |
