摘　　要：该文基于任意两个N×N Hadamard矩阵,构造出一类三元非周期零相关区序列集。与Donelan和O’Farrell的构造方法相比,该文构造出的序列具有较高的能量效率。又进一步构造出两个相互正交的具有非周期零相关区的三元序列集,这样就可以提供更多的能够在准同步CDMA系统中使用的序列。Based on two arbitrary Hadamard matrices of common size, a new class of ternary sequence with aperiodic zero correlation zone is presented. Different from the construction given by Donelan and O＇Farrell, the proposed method can generate sequences with higher energy efficiency. Furthermore, two of this kind of sequence sets are constructed which are mutually orthogonal, so that the number of available sequences for a Qs-CDMA system is increased.

关 键 词：准同步CDMA系统 零相关区序列集 HADAMARD矩阵 相互正交序列集
