无碰撞区跳频序列集的汉明相关函数在相关区内为零,可以消除跳频多址扩频系统中跳频信号在无碰撞区的相互干扰.基于矩阵置换提出了一种最大汉明相关值可灵活设定的无碰撞区跳频序列集的一般构造方法,该方法构造得到的跳频序列集具有较低的最大汉明相关值和较长的无碰撞区长度.作为一般构造法的一个特例,介绍了移位构造法. The Hamming correlation function of the non-collision zone hopping sequence set is zero in the correlation zone, which can eliminate the mutual interference of the frequency hopping signals in the collision-free zone in the frequency hopping multiple access spreading system. Based on the matrix replacement, a maximum Hamming A general construction method of the collision-free zone hopping sequence set can be set flexibly, and the set of frequency hopping sequences constructed by the method has a lower maximum Hamming correlation value and a longer collision-free zone length. As a general construction method A special case, introduced the shift construction method.
