摘　　要：提出了一种新的周期循环相关信号,即伪随机屏蔽二进阵列偶。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伪随机屏蔽二进阵列偶存在的组合允许条件,在此基础上,利用计算机搜索出若干体积小于22的伪随机屏蔽二进阵列偶。搜索结果表明:伪随机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于工程中。A new periodic correlation signal is proposed, called the pseudorandom punctured binary array pair （PPBAP）. The definitions of PPBAP are given and its transformation properties are also studied. To reduce the searching range and improve the searching efficiency of pseudorandom punctured binary array pair, some limited conditions of PPBAP are discussed. Many pseudorandom punctured binary ar- ray pairs less than 22 in volumes are searched. The searching results show that some pseudorandom punctured binary array pairs have high energy efficiency, thus they are used as synchronization codes and multi-user codes in engineering applications.
