摘　　要：在准同步CDMA系统中,使用零相关区域(ZCZ)序列能够避免共信道冲突和多址干扰。为了拓展二元ZCZ序列的空间范围,研究了一类特殊序列偶对的性质,并以这类特殊的序列偶对为初始矩阵,提出一类构造ZCZ序列偶集合的递归法。由这类方法构造出的ZCZ序列偶集合适于作准同步CDMA系统的扩频序列。In the quasi-synchronous CDMA systems, using the zero correlation zone （ZCZ） sequences can avoid the co-channel interference and the multi-access interference. In order to extend the space of binary ZCZ sequence, the properties of a kind of special sequence pairs is studied, and a type ofrecursion method for constructing ZCZ sequence pair set is presented by using the kind of special sequence pairs as the initialization matrix. The sets of ZCZ sequence pairs constructed from the method can be suitable for quasi-synchronous CDMA systems.
