摘　　要：最佳二进阵列在通信领域中有着广泛的应用,但由于其存在体积的限制,制约了它的应用范围,针对这种现象,提出了一种新的最佳离散信号,即准最佳三进阵列偶,给出了准最佳三阵列偶的定义和变换性质,研究了它的组合允许条件,分析了它与准最佳二进阵列偶、准最佳屏蔽二进阵列偶以及最佳三进阵列偶之间的关系,并用计算机搜索出部分小体积的准最佳三进阵列偶。实验结果显示准最佳三进阵列偶的存在范围非常广泛,为通信工程的应用提供了更多的选择。The perfect binary array is widely used in the field of communication engineering.However,the applications are constrained by the existing space.To overcome this limitation,a new perfect discrete signal is proposed,which is quasi-perfect ternary pairs.The definition and transform features of quasi-perfect ternary pairs are discussed,and its existing necessary condition is studied.This paper analyzes the relations between it and quasi-perfect binary array pairs,quasi-perfect punctured binary array pairs,perfect ternary array pairs.Many quasi-perfect ternary pairs with small size are searched with computer.Experimental results show that the existing space of quasi-perfect ternary pairs is very widespread, and more choices are provided for communication engineering.
