摘　　要：无碰撞区跳频序列集能够有效减轻通信中的多径干扰,在准同步跳频通信系统中具有广阔的应用前景。提出了两种新的无碰撞区跳频序列集构造的方法,在这种构造方法中,序列的个数和无碰撞区的长度是可以灵活变动的。由这两种方法构造的无碰撞区跳频序列集的频隙个数、序列长度、序列个数、无碰撞区长度、汉明相关值等参数均达到了理论界,是最优的无碰撞区跳频序列集。Frequency hopping sequence set with zero collision zone can effectively reduce the multipath in- terference in the communication and it has extensive application prospect in the quasisynchronous frequency hopping communication system. Two methods of constructing the frequency hopping sequence set with no hit zone are proposed in which the number of sequences and the length of no hit zone can be flexibly changed. All of the parameters consisiting of the number of frequency slot, the length of sequences, the number of sequences, the length of zero collision zone and the hamming correlation values of the frequency hopping sequence set with no hit zone constructed by these methods have reached the theory bound, which result in the optimal frequency hopping sequence set.
