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

Abstract

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 2^α10^β26^γ 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.
