Abstract

In this correspondence, a generic method of constructing optimal p²-ary low correlation zone sequence sets is proposed. Firstly p²-ary column sequence sets are constructed, then p²-ary LCZ sequence sets with parameters (pⁿ-1, p^m-1, (pⁿ-1)/(p^m-1),1) are constructed by using column sequences and interleaving technique. The resultant p²-ary LCZ sequence sets are optimal with respect to the Tang-Fan-Matsufuji bound.
