摘要

Z-complementary code sets (ZCCSs) are widely used in multi-carrier code-division multiple access (MC-CDMA) and multiple-input multiple-output (MIMO) communication due to their excellent correlation properties within a specific region around the in-phase position known as the zero correlation zone (ZCZ). In this paper, we introduce the concept of a partially m-shifted orthogonal complementary code, and use it to construct optimal ZCCSs by combining complete complementary codes (CCCs). The resulting optimal ZCCSs are not covered by existing literature.
