摘要: 为了减少搜索范围,提高计算机搜索效率,提出了一种新的周期循环相关信号,给出了其定义,并研究了其变换性质和频谱特性,给出了一些几乎最佳屏蔽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体积小于22的几乎最佳屏蔽二进阵列偶。搜索结果表明,几乎最佳屏蔽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: A new periodic correlation signal is proposed, APPBAP (Almost Perfect Punctured Binary Array Pair). The definitions of APPBAP and its transformation properties are presented. To reduce the searching range and improve the searching efficiency of almost perfect punctured binary array pair, limited conditions of APPBAP are discussed. Based on these limited conditions, many almost perfect punctured binary array pairs with small length no more than 22 are searched. The searching results show that almost perfect punctured binary array pairs have such high energy efficiency that they are feasible for engineering applications as synchronization codes and multi-user codes.

Key words: array pair, correlation, information theory, perfect signal
