摘　　要：介绍了以p进制码为复制信息,用平移复制生成复数值多相序列的方法,讨论了复制生成序列的性质和复制生成序列的相关函数,给出了2个生成序列的互相关函数值恒为0的条件,并给出了2个离散奎斯特恩逊函数之间互相关函数值恒为0的条件.最后给出了一个复制信息的选取准则,根据这个准则可以得到一个两两之间互相关函数值恒为0的序列族.The method of shift-copy generating multi-complex number sequence by p-ary code copy information is presented. The correlation function and property of sequence are also discussed. The condition that cross correlation function of two generating sequence is always zero is given. The condition that cross correlation function between two discrete Chresteson functions is equal to zero is given. At last, the selection criteria of copy information are given, according to which a sequence family can be found where correlation function is always zero.
