摘要:

提出了一种由一个完备序列的移位序列集和酉矩阵构造零相关区序列集的方法, 该方法主要通过适当地选择完备序列的移位序列做成的正交序列集, 结合相应阶数的酉矩阵进行序列扩展, 从而得到几乎最优和最优的2类零相关区序列集.

关键词: 完备序列, 零相关区序列集, 相关积, 酉矩阵

Abstract:

Two new methods for constructing zero correlation zone (ZCZ) sequence set from an arbitrary perfect sequence and unitary matrices are presented.The key of this method is to spread a perfect sequence by correlation product of the shift sequences set of the perfect sequence and corresponding unitary matrix. The new sequence sets are approximately optimal and optimal respectively with respect to the mathematical bound by using different choice of shift sequences set of perfect sequence.

Key words: perfect sequence, zero correlation zone sequence set, correlation product, unitary matrix
