Abstract：A construction of aperiodic Inter-Group Complementary (IGC) sequence sets is proposed based on orthogonal matrices. The Zero Correlation Zone (ZCZ) length of the proposed aperiodic IGC sequence set can be chosen flexibly, and the parameters are optimal in terms of the corresponding theoretical bound. Moreover, binary and polyphase aperiodic IGC sequence sets can be obtained utilizing binary and polyphase orthogonal matrices. The presented IGC sequences can work in both synchronous and asynchronous Code Division Multiple Access (CDMA) communication systems.
