New Constructions of Even-Length Type-II Z-Complementary Pairs

In this letter, we propose constructions of Type-II Even-Length binary Z-complementary pairs (EB-ZCPs) with parameters such as (3N1N2N3, 3N1N2N3 - 1) and ((N1N2)n L, (N1N2)n L - L + Z), respectively, where N1, N2, N3 are restricted to 2α10β26γ and n represents the times of iterations. The width of zero correlation zone (ZCZ) can reach or approach the theoretical upper bound, and the obtained Type-II EB-ZCPs have the low upper bound of peak-to-mean envelope power ratio (PMEPR), which can not be produced by existing constructions. Therefore, the constructions in this letter can provide more new types of ZCPs to suppress the potential asynchronous interference in broadband wireless communication systems.
