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。
In order to design frequency encode and frequency-hopping（FH） sequence in differential frequency- hopping（DFH） system, a differential frequency encode based on chaos mapping is provided, and Markov char- acter of frequency state transfer in frequency encode is analyzed. The statistical results show that the frequency- hopping sequences driven by chaos differential frequency encode have better uniformity and randomness, which is effective to construct DFH transfer function with higher linear complexity.
