摘要
基于正交矩阵,该文提出一类非周期组间互补序列集的构造法。构造的非周期组间互补序列集的零相关区长度可灵活设定,且参数达到了理论界限。通过选取二元或多相正交矩阵,可以得到二元或多相非周期组间互补序列集。构造的组间互补序列可以用于同步和非同步码分多址通信系统。
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.
