Abstract

Abstract: Best binary sequence pair exists in a lager scope than perfect binary sequence, for the sake of enlarging the address code selection of Quasi-Synchronization Code Division Multiple Access (QS-CDMA). Two methods of constructing sequence pairs set of asymptotic optimal Low Correlation Zone (LCZ) were proposed. A kind of asymptotic optimal LCZ sequence pairs set was constructed based on perfect binary sequence pair with modified Walsh sequences set (or m-sequence's cyclic shift sequences set) and a set generated by the cyclic shift sequences of a binary sequence pair with two-level periodic autocorrelation. The asymptotic optimal LCZ sequence pairs set constructed have more various parameters combinations. It can provide more choices for engineering application.

Key words: sequence pairs set of Low Correlation Zone (LCZ), perfect binary sequence pair, binary sequence pair with two-level periodic autocorrelation, asymptotic optimal, theory bound

摘要： 由于最佳二进序列偶的存在空间比最佳二元序列大，为进一步扩大准同步码分多址(QS-CDMA)系统的地址码选择范围，提出了两种构造渐近最佳低相关区(LCZ)序列偶集的方法。基于最佳二进序列偶与改造后的Walsh序列集（或m序列的循环移位序列集）和二元二值周期自相关序列偶的循环移位序列偶集，构造一类渐近最佳LCZ序列偶集，构造的渐进最佳LCZ序列偶集具有更多不同的参数组合，可为实际的工程应用提供更多的选择。
