摘要
为构造一类适用于跳频通信系统的跳频序列集,基于移位序列和交织法,提出了一种新的构造NHZ(无碰撞区)跳频序列集的方法。该方法得到的NHZ跳频序列集的参数可以达到理论界限,是一类最优NHZ跳频序列集,并且参数可以灵活设定。与已有的方法相比,得到的NHZ序列集中序列长度大于频点个数,该类NHZ序列集可以适用于更多的场合。
On the basis of shift sequence and the interleaving technique, a novel method for the construction of No-Hit-Zone （NHZ） frequency bopping sequence sets suitable for frequency hopping communication systems is proposed in this paper. The resultant parameters of the NHZ frequency hopping sequence sets are optimal in respect to the Peng-Fan-Lee bounds and they can be flexibly set. Different from the existing ones, these NHZ sequence sets have periods twice as much as the number of fre- quency points, applicable to still more occasions.
