摘　　要：讨论了Turbo码调制技术及其文献中的缺陷 ,研究了Turbo码与空时编码中的STCM结合问题 ,通过仿真实验与比较 ,证明了基于Turbo码的STCM系统具有性能优势 。At first, this paper discusses the turbo code modulation technique, and some problems in the literature published are analyzed. Then the turbo STCM that combines the turbo code and STCM is studied. We investigate transmit and decode schemes of the turbo STCM. The simulation results, through the comparison with turbo code modulation and STCM system, prove the performance advantages of the turbo STCM, and show that the turbo STCM can satisfy the requirements of wireless high rate data communication in indoor and low mobility environment.
