通过对互补序列的多个移位版本进行交错，提出了一种构造群间互补序列的新方法。所得到的序列集在每个序列群中都具有零相关带（ZCZ）性质，并且来自不同序列群的任意两个序列都具有理想的周期互相关性质。当选择合适的移位序列时，构造的IGC序列集在相应的理论界上是最优的。与现有的IGC序列构造相比，所提出的构造方法不仅可以提供灵活的ZCZ宽度，还可以提供灵活的单元序列长度，为IGC无线通信系统的设计和实现提供了更大的自由度。
By interleaving multiple shift versions of complementary sequence, a new method of constructing inter-group complementary (IGC) sequences is proposed. The resultant sequence set has zero correlation zone (ZCZ) properties in each sequence group and any two sequences from different sequence groups possess ideal periodic cross-correlation properties. When a suitable shift sequence is chosen, the constructed IGC sequence set will be optimal in terms of the corresponding theoretical bound. Compared with the existing constructions of IGC sequences, the proposed construction method may provide not only flexible ZCZ width but also flexible element sequence length, which will ensure a more freedom for the design and realization of IGC wireless communication systems.
