几乎最佳三进序列偶理论研究

摘要

提出一种具有良好自相关特性的周期相关信号,即几乎最佳三进序列偶,进一步丰富和完善了序列偶最佳相关信号理论.给出了几乎最佳三进序列偶的定义,研究了它的变换性质,并给出了它的一些存在的必要条件,同时研究了序列偶的谱特性,得到了序列偶的主、副峰值与每个序列的奇数位、偶数位元素之和的关系.%Almost perfect ternary sequence pairs,a new periodic correlation perfect signal is defined. This signal enriches the theory of sequence pairs.The definition of the almost perfect ternary sequence pairs and its transformation properties are presented, and the necessary conditions for the almost perfect ternary sequence pairs are given. The Fourier spectrum characters of almost perfect ternary sequence pairs are studied. The relation of main peak, vice-main peak of sequence pairs and the distributions of sequences' elements are deduced.
