| 摘 要： | 为了克服对偶法生成宽间隔跳频随机序列的缺点,基于m序列,提出非线性模d法,利用非连续抽头模型,生成宽间隔跳频随机序列.比较了对偶法生成的跳频序列和非线性模d法生成的跳频序列的自相关性能和互相关性能等.计算结果表明,非线性模d法是对偶法的明显改进,其生成序列的随机性、抗干扰性都有明显改善,且相关性能接近于最佳跳频序列的相关性能.

| Abstract: | In order to overcome the shortcoming of dual sub-bands method,based on m-sequence,the frequency hopping(FH) sequences with minimum gap are constructed by using of non-continual select model and non-linear& mod d method.Hamming correlation of FH sequences constructed with dual sub-bands method or non-linear &mod d method is compared.The experimental results show that non-linear &mod d method is much better than dual sub-bands method,the randomness and anti-interruption of sequences is improved,and its correlation approaches that of optimal FH sequences. |
