New Construction of Z-Optimal Type-II Even-Length Quadriphase Z-Complementary Pairs

抄録

Type-II Z-complementary pairs (ZCPs) play an important role in suppressing asynchronous interference in a wideband wireless communication system where the minimum interfering-signal delay is large. Based on binary Golay complementary pairs (BGCPs) and interleaving technique, new construction for producing Z-optimal Type-II even-length quadriphase ZCPs (EL-QZCPs) is presented, and the resultant pairs have new 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.
