This letter presents a direct construction of cross Z-complementary sequence sets (CZCSSs), whose aperiodic correlation sums exhibit zero correlation zones at both the front-end and tail-end shifts. CZCSS can be regarded as an extension of the symmetrical Z-complementary code set (SZCCS). The available construction of SZCCS has a limitation on the set size, with a maximum set size of 8. The proposed generalized Boolean function based construction can generate CZCSS of length in the form of non-power-of-two with variable set size $2^{n+1}$, where each code has $2^{n+1}$ constituent sequences. The proposed construction also yields cross Z-complementary pairs and cross Z-complementary sets with a large number of constituent sequences compared to the existing work.

翻译：本信展示了跨Z补充序列(CZCSS)的直接构造,这些序列的周期性相关总和在前端和尾端之间显示零相关带。 CZCSS可被视为对称Z补充代码集的延伸。 SZCSCS的现有构造对设定尺寸有一定的限制,设定的最大尺寸为8. 拟议的基于普惠布林功能的构造可产生以非二强形式出现的CZCSS,其设定大小为2 ⁇ n+1美元,其中每个代码各有2 ⁇ n+1美元组成序列。与现有工程相比,拟议的建筑还产生跨Z补充对子和跨Z补充组,其组成序列众多。
