New Two-Dimensional Z-Complementary Array Sets with Low Column Sequence PMEPRs

Two-dimensional (2D) array sets with good correlation properties have attracted tremendous research attention in wireless communications. This paper studies an innovative approach for the direct construction of 2D Z-complementary array sets (2D-ZCASs) based on 2D generalized Boolean functions. The proposed construction method stands out by offering increased flexibility in parameter settings compared to current state-of-the-art methods. Additionally, we study the peak-to-mean envelope power ratio (PMEPR) characteristics of the column sequences of the generated 2D-ZCASs. Notably, this investigation reveals that the PMEPR values of these column sequences are effectively upper-bounded by two.
