AI总结：
该研究提出一种基于CCC与相互正交单模序列Kronecker积的任意长度II型ZCCS构造方法，采用Barker序列降低特定场景下的PMEPR，其列序列PMEPR上界小于2，还生成了PMEPR更低的新长度II型ZCP和ZCS，可应用于低PMEPR的MC-CDMA系统。
摘要：
在这篇论文中，我们提出了一种具有任意序列长度的II型Z互补码集（ZCCS）的新型构造方法，该方法利用完全互补码（CCC）与相互正交的单模序列之间的Kronecker积实现。在该构造中，我们采用Barker序列来降低特定长度序列的行序列峰均包络功率比（PMEPR），以及特定码规模下的列序列PMEPR。所提出的II型ZCCS的列序列PMEPR上界小于2。该构造还贡献了新长度的II型Z互补对（ZCP）和II型Z互补集（ZCS）。此外，这些新型II型ZCP的PMEPR也低于现有的II型ZCP。
英文摘要：
In this letter, we propose a novel construction of type-II $Z$-complementary code set (ZCCS) having arbitrary sequence length using the Kronecker product between a complete complementary code (CCC) and mutually orthogonal uni-modular sequences. In this construction, Barker sequences are used to reduce row sequence peak-to-mean envelope power ratio (PMEPR) for some specific lengths sequence and column sequence PMEPR for some specific sizes of codes. The column sequence PMEPR of the proposed type-II ZCCS is upper bounded by a number smaller than $2$. The proposed construction also contributes new lengths of type-II $Z$-complementary pair (ZCP) and type-II $Z$-complementary set (ZCS). Furthermore, the PMEPR of these new type-II ZCPs is also lower than existing type-II ZCPs.
