摘　　要：The paper presents a kind of reasonable structure for implementing MQAM T-TCM based on the principles of turbo codes and TCM for the first time. It can also be expanded to PSK T-TCM system, and the corresponding decoding algorithm is derived. By computer simulation,its performance is analyzed. The results show that T-TCM takes the advantages of turbo codes and TCM technology, and is a kind of bandwidth-efficient coded-modulation technique obtaining high coding gain. So, in the future, T-TCM would be applied in many fields.The paper presents a kind of reasonable structure for implementing MQAM T-TCM based on the principles of turbo codes and TCM for the first time.
