摘要
本文通过两个实例描述了基于多维信号星座的多级网格编码调制方式的设计方法,并详细讨论了格分割链和星座的构造以及二元卷积码的选择等有关问题。
An approach for designing multilevel trellis coded modulation schemes based on multidimensional signal constellations is described through two examples. We discussed some related problems in detail, such as, how to construct chains of lattice partitioning and constellations, and how to select binary convolutional codes.
