Abstract :
In this paper, we introduce two new constructions of zero correlation zone (ZCZ) sequence sets, which are based on interleaved perfect sequences and affine transformations. The resultant sequence sets have not only larger family size and longer period, but also are more flexible when choosing the length of ZCZ, compared with the known constructions. One of them is optimal or almost optimal with respect to Tang-Fan-Matsufuji bound.
