摘　　要：针对已有方法生成跳频图案少、频隙利用率低等缺点,提出了一种新的基于m序列宽间隔跳频图案的生成法WIDBS法,其生成序列的性能相对于对偶法有明显提高。通过计算机仿真,表明该宽间隔跳频序列具有较好的汉明相关性,接近最佳跳频序列族。In order to overcome the defects of few hopping pattern and low use ratio of frequency, a new arithmetic named WIDBS, based on m-secquence is proposed. Compared with dual sub-bands method, the Hamming correlation is improved obviously. The result of simulation shows that the wide gap FH cede sequence with a good properties of Hamming correlation approaches that of optimal FH sequences.
