摘　　要：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。In this paper,we present a simple method for generating the decimal chaotic frequency hopping sequences based on the cosine mapping method and analyze the performance of the chaotic frequency hopping sequences.The calculation results processed by C program show that the performance of these sequences is good.At last,we utilize DSP to achieve a chaotic frequency hopping sequence.Then we use the method of given minimum gap to improve the performance of given gap greatly.
