Constructions of Z-Periodic Complementary Sequence Set with Flexible Flock Size

摘要

Based on orthogonal matrices, two constructions of Z-periodic complementary sequence set are introduced in this letter. The two proposed approaches can provide flexible choices for the flock size of the Z-periodic complementary sequence set, which cannot be obtained by known methods. The parameters of resultant Z-periodic complementary sequence sets are (M,N)PCS^{NM_1}_{M_2} and (M,N-1)PCS^{NN_1}_{M_2} respectively, which are all optimal when N_1
