摘要
本文研究了Turbo码与网格编码调制(Trellis Coded Modulation,TCM)相结合的编码调制技术,给出了Turbo码与TCM相结合的调制方案,对Turbo码与TCM调制方案进行了计算机仿真,仿真结果表明,其性能要优于传统的采用卷积码的TCM调制。
In this paper, we discussed the modulation techniques for combining turbo code with TCM. We gave its modulation schemes, We simulated its modulation schemes by using computer, provided that its performance is better than the TCM by using convolutional codes.
