摘要: 为同步长周期的跳频码序列,必须使用实时时间TOD。一种新的眼光是将跳频码发生算法看作是对TOD这一特殊信息序列的分组加密变换。单调递增的计数式TOD是目前常用的TOD序列形式,然而,现有的跳频码发生算法并不适应长周期、单调递增计数式TOD的使用,该文讨论了分析、改造跳频码序列发生算法使之适合长周期单调递增计数式TOD的需求、又保持良好跳频特性这一重要任务。

Abstract: It is necessary to use the reference real time TOD(Time Of Date) for synchronizing a hopping sequence with long period. There is a new view that the generation of hopping codes is a process in which the special information sequences TOD are translated by a block encoding. Today monotonously increasing TOD is a common form, but there are collides between existing generating algorithm of hopping code and monotonously increasing TOD with long period. A important task of study on generating algorithm of hopping code which is suitable for monotonously increasing TOD with long period and keeps good properties is discussed in the paper. -
