Abstract In 2000, Tang, Fan and Matsufuji presented the theoretical bound of an (L, M, Zcz)-ZCZ sequence family is Zcz≤L/M-1. In this paper, for given positive integers n and L, a construction algorithm of interleaved ZCZ sequence families is proposed, by which a class of binary (2n+1L,2L,2n-1)-ZCZ sequence families can be generated from an orthogonal sequence family composed of L sequences with period L. If n≥2 and 4∣τ, the correlation value between even-number-indexed sequences and odd-number-indexed sequences with shift τ of this sequence family is zero. Furthermore, choose different orthogonal sequence families or different shift sequences, different ZCZ sequence families can be generated by this construction algorithm.
