Interleave structure is a well-known period extending method, by which we can extend the period of an original ZCZ sequence family to generate a long period ZCZ sequence family. In this paper, we first present two basic period extending methods: 1. when period extends, the sequence number keeps unchangeable, while the zero correlation zone length extends; 2. when period extends, the zero correlation zone length keeps unchangeable or slightly decreased, while the sequence number extends. Then we propose the concept of D-matrix, by which to determine the shift sequence in the interleaved structure and to calculate the zero correlation zone length of interleaved ZCZ sequence families. In Section 3 and Section 4, two generating algorithms of interleaved ZCZ sequence families and the corresponding optimal D-matrix are proposed.
