| 摘 要： | 对改进型 L ogistic- Map映射作了改进 ,对基本混沌序列两端分布密集的缺点有了较大幅度的改善 ,将所得到的混沌序列和修正了的对偶频带法相结合 ,又可以产生一类混沌宽间隔FH- CDMA序列。对该序列进行仿真验证的结果显示 ,新序列分布比较均匀且有较好的汉明相关性 ,而且数量极多

| Abstract: | This paper improves on the improved Logistic Map maps,and gets rid of the shortcoming of chaotic sequence distributing thick and fast at two ends.Combining with new chaotic sequence and dualistic frequency band,a kind of chaotic FH CDMA sequence with broad distance is proposed.Through emulations by computer,we find that this kind of sequences distribute equably,the Hamming pertinency are excellent,and the number of the sequences is much more.Using this kind of sequences as access code in FH CDMA system is a good choice. |
