A novel construction of ZCZ sequence pairs set from interleaving perfect sequence
Longye Wang · 2012
To reduce the limit on the relevant parameters during constructing zero correlation zone (ZCZ) sequence pairs set and enrich the choice of spreading sequence, a new method was proposed to construct almost optimal sequence pairs set with ZCZ. Based on the interleaved technique, a novel ZCZ sequence pairs set can be obtained from an arbitrary perfect sequence with a period longer than 4. And the ZCZ width and period of the new sequence pairs set can also be extended by recursive algorithm. The new sequence pairs set approaches closely the mathematical bound, and can successfully provide CDMA communication without co-channel interference.
