Complete complementary codes (CCCs) have found a number of practical applications in wireless communications owing to their perfect aperiodic auto-correlation and cross-correlation properties. In particular, an important application of CCCs is in interference-free multi-carrier code-division multiple-access (MC-CDMA) systems. The available number of complementary codes determines the system capacity. To enlarge the system capacity, this paper focuses on constructing multiple CCCs with inter-set zero cross-correlation zone (ZCCZ) property based on generalized Boolean functions (GBFs). To the best of our knowledge, such multiple CCCs have not been reported in the literature. The obtained multiple CCCs can provide advantages in applications to MC-CDMA systems with multiple cells. As a byproduct, optimal aperiodic Z-complementary code sets (ZCCSs) with low peak-to-mean envelope power ratio (PMEPR) can be derived by combining these CCCs.

具有组间零互相关区的多个完全互补码

由于其完美的非周期性自相关和互相关特性，完全互补码 (CCC) 在无线通信中得到了许多实际应用。特别是，CCC 的一个重要应用是在无干扰多载波码分多址 (MC-CDMA) 系统中。可用的互补代码数量决定了系统容量。为了扩大系统容量，本文着眼于基于广义布尔函数（GBFs）构建具有集间零互相关区（ZCCZ）特性的多个CCC。据我们所知，文献中尚未报道过此类多个 CCC。获得的多个CCC可以为具有多个小区的MC-CDMA系统的应用提供优势。作为副产品，
