| 摘 要： | 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.

| Abstract: | For the frequency hopping sequence sets with no-hit zone, the values of their Hamming correlation functions in the no-hit zone equal to zero, which can be used to eliminate the mutual interference in a frequency-hopping code-division multiple-access communication system. Based on the matrix permutation, a general construction of frequency hopping sequence sets with no-hit zone and flexible maximum Hamming correlation value is presented in this paper. Using the proposed method, frequency hopping sequence sets with lower hamming correlation and longer no-hit zone can be obtained. In addition, as a special case of the general method, a construction based on cyclic shift is introduced. |
