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.
