Abstract

This paper proposes a new construction method of binary sequence pair sets with zero correlation zone (ZCZ) in which the correlation functions of sequence pairs are zero, based on difference set pair, a new concept of combinatorial mathematics. With the extension of sequence length, the sets achieve the theoretical upper bound. These ZCZ sequence pairs can be applied to the generalized quasi-synchronous multiple-access system (QS-CDMA) to reduce and eliminate multiple access interference and co-channel interference.
