Research of ZCZ array pair and its construction methods

Abstract

A new quasi-perfect discrete signal—ZCZ array pair which has good periodic correlation property and its con-struction method was proposed. Based on perfect array pair and orthogonal matrix, ZCZ array pairs set with certain vol-ume, family size and zero correlation zone can be synthesized through row or column interleaved technique when suitable shift sequences are selected. Except the binary case, the proposed technique can be applied to synthesize polyphase ZCZ array pairs set also. These ZCZ array pairs sets are feasible as multi-user signal, and extend the selectable scope of two-dimension perfect discrete signal.
