Abstract

Z-complementary code sets (ZCCSs) are widely employed in multi-carrier spread spectrum and MIMO communication systems. This study introduces the concept and construction of generalized column orthogonal (GCO) matrices to develop new classes of Z-paraunitary (ZPU) matrices. Utilizing the equivalence between ZCCSs and ZPU matrices, novel polyphase ZCCSs are constructed. The flexible sizing of GCO matrices allows for a wide range of parameter configurations. The proposed method enables the derivation of optimal ZCCS parameters that are unattainable in existing literature. Furthermore, by designing GCO matrices whose column vectors exhibit low peak-to-mean envelope power ratio (PMEPR), ZCCSs with column sequence PMEPR no greater than 2 are achieved. This work expands the repertoire of code options for various communication scenarios.

基于广义列正交矩阵的z互补码集的新构造

z互补码集（ZCCSs）广泛应用于多载波扩频和MIMO通信系统中。本文引入广义列正交矩阵（GCO）的概念和构造，发展了一类新的z -准酉矩阵（ZPU）。利用ZCCSs与ZPU矩阵之间的等价性，构造了新型多相ZCCSs。GCO矩阵的灵活大小允许广泛的参数配置。提出的方法可以推导出现有文献中无法获得的最优ZCCS参数。此外，通过设计列向量具有低峰均包络功率比（PMEPR）的GCO矩阵，获得了列序列PMEPR不大于2的zccs。这项工作扩展了各种通信场景的代码选项库。
