论文摘要
与完整的互补代码（CCC）相比，准融合序列集（QCSS）吸引了持续的研究兴趣，以同时支持更多活跃用户。在本文中，我们研究了由多个CCC组成的新型QCSS。我们为这种类型的QCSS得出了一种新的Aperiodic相关性下限，该QCSS比QCSS的现有界限更紧。然后，我们提出了具有较小字母大小和低最大相关幅度的此类QCSS的系统构造，还表明构建的Aperiodic QCSS可以通过渐近造成的新派生结合。
Quasi-complementary sequence sets (QCSSs) have attracted sustained research interests for simultaneously supporting more active users in multi-carrier code-division multiple-access (MC-CDMA) systems compared to complete complementary codes (CCCs). In this paper, we investigate a novel class of QCSSs composed of multiple CCCs. We derive a new aperiodic correlation lower bound for this type of QCSSs, which is tighter than the existing bounds for QCSSs. We then present a systematic construction of such QCSSs with a small alphabet size and low maximum correlation magnitude, and also show that the constructed aperiodic QCSSs can meet the newly derived bound asymptotically.
