Abstract

A family of sequences with zero correlation zone, which is shortly called ZCZ set, can provide CDMA systems without co-channel interference nor influence of multipath. We present two types of ZCZ sets of nonbinary sequence pairs, which achieve the upper bound of family size for length and zero correlation zone. One, which is produced by use of a perfect complementary pair and an orthogonal code, can change zero correlation zone, while the upper bound is kept. The other, which is generated by use of a newly defined orthogonal pair and an orthogonal code, can offer such CDMA system as a binary ZCZ set is used.
