摘要: 该文提出一种新的移位序列的构造方法，通过给移位序列赋予不同的值，得到一类新的移位序列。基于这种移位序列，利用交织法得到了一类具有灵活相关区长度并且参数接近甚至达到理论界限的低零相关区序列集，扩大了交织法的应用范围，得到了更多的适用于准同步CDMA系统的扩频序列集。

Abstract: A new method of construction of shift sequences is presented by setting different parameters to shift sequences. With these shift sequences, a class of sequence sets is got with flexible zero or low correlation zone whose set sizes can reach or approach the theoretical bound through interleaving technique, the proposed method can be used to construct more sequence sets suitable for QS-CDMA systems. -
