摘要

受Levenshtein思想的启发，我们在加权均方非周期相关中引入了低相关区。然后给出了具有低相关带的拟互补序列集(LCZ-QCSS)的下界。我们讨论了所提界的紧性条件。结果表明，在某些条件下，所提出的界比LCZ-QCSS的Liu-Guan-Ng-Chen界更紧。

A Tighter Correlation Lower Bound for Quasi-Complementary Sequence Sets with Low Correlation Zone

Inspired by Levenshtein’s idea, we introduce the low correlation zone to the weighted mean square aperiodic correlation. Then we derive a lower bound for quasi-complementary sequence sets with low correlation zone (LCZ-QCSS). We discuss the conditions of tightness for the proposed bound. It turns out that the proposed bound is tighter than Liu-Guan-Ng-Chen bound for LCZ-QCSS under some conditions.
