New Construction of Z-optimal Type-Ⅱ Even-length Quadriphase Z-complementary Pairs

摘要

Type-Ⅱ Z-complementary pairs (ZCPs) play an importantrole in suppressing asynchronous interference in a wideband wireless communicationsystem where the minimum interfering-signal delay is large.Based on binary Golay complementary pairs (BGCPs) and interleavingtechnique, new construction for producing Z-optimal Type-Ⅱ even-lengthquadriphase ZCPs (EL-QZCPs) is presented, and the resultant pairs havenew lengths in the form of 2×2~α10~β26~γ(α,β,γ non-negative integers),which are not included in existing known Type-Ⅱ EL-QZCPs.
