摘　　要：对Suehiro提出的多相正交序列的构造方法进行了简要地介绍和分析,通过简化生成矩阵,达到了避免重复,直接产生独立序列的目的。在此基础上,本文通过对该多相序列的循环移位与正交复合,提出了一组新的完全互补码,其方法简单,生成容易,且具有较强的灵活性。Firstly,the construction of multiphase orthogonal sequences proposed by Suehiro is presented briefly. Then,in order to exclude repeated sequences from the sequence set, we give a direct idea of producing individual sequences simply by restricting some terms. In addition, we proposed a new method of constructing complete complementary codes by cyclically shifting multiphase orthogonal sequences and combining orthogonal matrix, this concise method extends the number of complete complementary codes and improves the flexibility of the system design.
