摘要
TCM(Trellis Coded Modulation)好码的具体结构多种多样,该文从网格图的角度分析了TCM好码可能的结构。并应用分析结果构造了一种TCM好码的构造算法。它不仅缩小了所搜范围,提高了搜索效率,而且得到的结果性能较好。
There are various structures of good TCM codes. And based on the trellis map, the most possible structure of good TCM codes is analyzed. From the results, a construction algorithm is then designed. Since the searching space is greatly reduced, this method has higher efficiency and can produce codes of high performance compared with the classic algorithm.
