摘　　要：本文根据Ｔｕｒｂｏ编码和ＴＩＭ原理，提出一种更为合理的ＭＱＡＭ Ｔ－ＴＣＭ实现结构，这种实现方式也可推广到ＰＳＫ Ｔ－ＴＣＭ系统，并导出与其相应的译码算法。通过计算机模拟对其性能进行了分析，证明了改进结构的正确性。The paper proposes a kind of reasonable structure for implementing MQAM T-TCM based on the prin- ciples of turbo codes and TCM It can also be expanded to PSK T-TCM system, and the corresponding decoding algorithm is derived. By computer simulation, its performance is analysed, and the validity of the modified struc- ture is vetified.
