2种最佳离散信号的构造方法

Two perfect methods of constructing discrete signals

为了构造更多的几乎最佳二进阵列偶和几乎最佳屏蔽二进阵列偶,扩大其应用范围,采用复合乘积法、二维周期乘积法以及折叠变换法,利用最佳二进阵列偶、几乎最佳二进阵列偶和几乎最佳屏蔽二进阵列偶等已知的最佳离散信号,可以构造出大量的几乎最佳二进阵列偶和几乎最佳屏蔽二进阵列偶等新的具有良好循环相关特性的最佳离散信号.实验证明这2种最佳离散信号不受体积为4t2的束缚,从而找到更多的最佳离散信号实例.

To construct more almost perfect binary array pairs and almost perfect punctured binary array pairs, and to expand their scope of application, the complex product, two-dimensional cycle of product and folding transform method were adoped, and by using the known perfect discrete signal, large amounts of optimum signal of almost perfect binary array pairs and almost optimal shielding binary array with new and good characteristics related circulation could be constructed. The two kinds of optimum discrete signal gets rid of the limitation of volume 4t^2, so that more examples of the optimum signal can be found.
