由选定信号集边界的信号星座成形用于降低该星座的平均能量。在Voronoi星座中,作为此成形格的Voronoi区域用于形成此星座边界。此时,该星座点集按此成形格为模矢量相加形成一个群。这种性能用于选择此信号点。本文将讨论基于成形格D_N及D_N的Voronoi星座的各种特性,并求出在二维子空间中所导入的概率分布。亦提供了另一种作为选定码结构方法的首标编码方案。这种码在某种意义上由利用具不等概率的该子空间上的点而模拟着边界效应。
The signal constellation at the boundary of the selected signal set is used to reduce the average energy of the constellation. In the Voronoi constellation, the Voronoi region as this shaped cell is used to form this constellation boundary. At this point, the constellation point set according to the forming grid for the modal vector sum to form a group. This property is used to select this signal point. This article will discuss various properties of the Voronoi constellation based on the forming lattices D_N and D_N and find out the probability distribution introduced in the two-dimensional subspace. Another header coding scheme is also provided as a method of selecting a code structure. This code mimics the boundary effect in a sense by using points on the subspace with unequal probabilities.
