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.
