The trellis diagram of the natural state realization of the group code and the path through the trellis diagram of the group code are constructed. 构造了此类群码的自然状态实现的格子图和它的通过其格子图的途径;
The state realization and the trellis diagram of a group code defined on lattices are studied. 将其建立在全序集上的概念推广到格上,研究了定义在格上群码的状态实现和格子图;
