将伪随机序列应用于零相关区(ZCZ)序列偶中,提出了一种新的ZCZ三元序列偶集的构造方法。通常的ZCZ序列集构造是基于最佳序列的,而此方法是将伪随机序列和正交矩阵相结合,通过选择适当的移位序列,经交织变换生成具有一定长度、序列数目和零相关区的三元序列偶集。使用新方法构造出的ZCZ三元序列偶集具有较大的容量,可以更好地满足实际工程的需要。
Pseudorandom sequence was used in zero correlation zone(ZCZ) sequence pairs, and then a new construction method for ZCZ ternary sequence pairs set was presented. The general construction method of ZCZ sequence set was based on perfect sequence, but the new construction method was based on pseudorandom sequence and orthogonal matrix ZCZ ternary sequence pairs set with certain length, family size and zero correlation zone could be synthesized through interleaved transformation when suitable shift sequences were selected. The capacity of ZCZ ternary sequence pairs set constructed by the proposed method is so large that it can satisfy requirements of engineering applications.
