提出了一种基于余弦映射法产生十进制混沌跳频序列的方案,并对此方案所产生的十进制混沌序列在跳频通信系统中的性能进行了分析,包括用C语言进行模拟计算,使性能达到良好。在此基础上,通过查表和使用DSP使该方案得到落实并结合对偶宽间隔法产生了宽间隔的跳频序列,使跳频间隔得到了大大的改善。 A scheme based on the cosine mapping method to generate the decimal chaotic FH sequences is proposed. The performance of the chaos sequence in the FH system is analyzed, including the simulation in C language, good. On this basis, through the look-up table and the use of DSP to make the program be implemented and combined with dual wide interval method to produce a wide frequency hopping sequence, the frequency hopping interval has been greatly improved.
