| 摘 要： | 本文提出了一种新的周期循环相关信号,即几乎最佳二进阵列偶.文中给出了其定义,并研究了它的变换性质,为了减少搜索范围,提高计算机搜索效率,文中研究给出了一些几乎最佳二进阵列偶存在的组合允许条件,在此基础上,利用计算机搜索出了若干小体积的几乎最佳二进阵列偶.搜索结果表明几乎最佳二进阵列偶具有很高的能量效率,因而可以作为同步码或多用户码应用到工程中.

| Abstract: | This paper proposes a new periodic correlation signal,which is almost perfect binary array pair(APBAP).We present the definitions of APBAP and its transformation properties.To reduce the searching range and improve the searching efficiency of almost perfect binary array pair,limited conditions of APBAP are discussed.Based on these limited conditions,we search out many almost perfect binary array pairs with small length no more than 20.The searching results show that almost perfect binary array pairs have such high energy efficiency that they are feasible for engineering applications as synchronization codes and multi-user codes. |
