摘要
详细分析了一种logistic满映射产生跳频序列的方法,将小数部分二进制化,然后按行比特抽取与列比特抽取交替抽取方式进行,最后利用非线性模D法进行宽间隔处理,这样经过两次非线性处理构造跳频图案,它的抗干扰、抗截获的性能得到很好的改善,对于保密通信系统性能也有极大提高。交替处理方案可以减少迭代次数也能进行非线性化处理。仿真实验结果表明其性能优良,非常适合跳频多址通信中应用。
This paper analyzes in detail a method that the full logistic chaotic map produces hopping sequence.This method uses decimal-to-binary conversion and bit-line extraction by turns and D non-linear mode to deal with the wide interval,finally forming the frequency-hopping patterns.Simulation results show that it is excellent in performance,and could greatly improve the performance of chaotic code patically in anti-interference and anti-interception,thus is very suitable for frequency hopping applications in multiple access communication and secure communication.
