This paper presents the construction of a class of sequence sets with zero-correlation zones, called zero-correlation zone sequence sets, that can reach the up per bound on the sequence set size. The proposed sequence sets of ternary sequences, which can be constructed by a ternary perfect sequence, can successfully provide CDMA communication without co-channel interference. In an ul trasonic synthetic aperture imaging system, the proposed sequence set can improve the signal-to-noise ratio of the acquired image.
