The article introduces a construction method for 2-D Z-complementary array code sets with flexible parameters, focusing on wireless communication applications like massive MIMO. It starts by discussing the importance of 2-D arrays with good correlation properties in wireless communication systems. The proposed method involves constructing inter-group complementary code sets using multivariable functions, leading to the creation of 2-D Z-complementary array codes and sets. Special cases like 2-D Z-complementary array pairs are also explored. The article highlights the advantages of the proposed construction in terms of peak-to-mean envelope power ratio (PMEPR) and its application in multi-carrier code division multiple access (MC-CDMA) systems. Additionally, derivations of Golay complementary array sets and Golay complementary sets from the proposed construction are discussed, emphasizing their use in omnidirectional precoding for massive MIMO systems. The article concludes by comparing the proposed constructions with existing ones based on performance metrics.
