摘要
提出了一种新的基于交织法构造最优低/零碰撞区跳频序列集的方法。此方法构造出的低/零碰撞区跳频序列集合均是移位不等价的,各集合中的序列均达到理论界限,相关区长度在满足一定条件下可灵活选取。该方法可构造出多个最优低/零碰撞区跳频序列集合,扩展了集合的数目,使其可以应用于多个不同的用户群体。
Based on the interleaving technique, a newmethod for constructing low/zero hit zone frequency hopping sequence setsis proposed in this paper. The resultant LHZ/NHZfrequency hopping sequence sets are not shift and equivalent and all the sequencesets are within the theoretical bound. The length of correlation zone can be flexibly set under certain conditions. This method couldconstruct multiple optimal NHZ/LHZ frequency hopping sequence sets, extend the number of assembles and be applied to manydifferent users.
