V.32标准下的32QAM-TCM仿真

32QAM-TCM Simulation under ITU-T V.32 Standard

文章在介绍TCM基本原理的基础上,讨论了V.32标准下32QAM-TCM仿真的具体细节,包括差分编码、卷积编码及维特比译码等部分,并给出仿真的结果,说明了TCM编码对系统性能的改善。

With an introduction of the basic principle of TCM（Trellis Coded Modulation）, the specific details of 32 QAM - TCM simulation under ITU - TV. 32 standard are discussed in the paper, including the differential encoding, convolution encoding and Viterbi decoding, ＇and the simulation results, which shows TCM Coding can improve the performance of the system.
