The one-dimensional (1-D) Golay complementary set (GCS) has many well-known properties and has been widely employed in engineering. The concept of 1-D GCS can be extended to the two-dimensional (2-D) Golay complementary array set (GCAS) where the 2-D aperiodic autocorrelation of constituent arrays sum to zero except for the 2-D zero shift. The 2-D GCAS includes the 2-D Golay complementary array pair (GCAP) as a special case when the set size is 2. In this paper, 2-D generalized Boolean functions are introduced and novel constructions of 2-D GCAPs, 2-D GCASs, and 2-D Golay complementary array mates based on generalized Boolean functions are proposed. Explicit expressions of 2-D Boolean functions for 2-D GCAPs and 2-D GCASs are given. Therefore, they are all direct constructions without the aid of other existing 1-D or 2-D sequences. Moreover, for the column sequences and row sequences of the constructed 2-D GCAPs, their peak-to-average power ratio (PAPR) properties are also investigated.
翻译：2D GCAS 包含 2D GCAP 和 2D GCAS 的 2D 函数。 因此,它们都是直接构造的,没有其他现有1-D 或 2D 序列的帮助。 此外,对于2D GCAP 结构的柱形序列和行序列,它们也是最高至最高值。
