摘　　要：在高速率的OFDM设计中,MQAM-TCM调制已被广泛采用。本文提出了一种适用于OFDM的混合 QAM-TCM设计,并对两种不同的实现方案与MQAM-TCM进行了仿真比较,结果表明混合QAM-TCM的性能优于 MQAM-TCM。MQAM-TCM has been widely used in high rate OFDM design. Based on the practical application, the paper presents hybrid QAM-TCM design fitting for OFDM. Further more, two different implementation scheme for hybrid QAM-TCM and MQAM-TCM are simulated and compared. The results shows that performance of hybrid QAM-TCM has advantage over MQAM-TCM.
