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.
針對差分跳頻繫統頻率編碼及跳頻序列的設計問題,提齣利用混沌映射構造差分頻率編碼,併分析瞭其頻率狀態轉移的Markov性和編譯碼特點.最後檢驗瞭基于混沌映射的差分跳頻頻率編碼的統計性能,結果錶明,其產生的跳頻序列具有較好的均勻性和隨機性,不失為一種具有較高線性複雜度的有效的差分跳頻轉移函數.

@@@@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.
