从欧氏距离分析TURBO网格编码调制

An Analysis of Parallel Concatenated Trellis Coded Modulation Based on Euclidean Distance

提出了一种用欧氏距离分析TURBO网格编码调制 (TTCM )的构成及误码率的方法 ,以最大自由欧氏距离 (MFED)为判据 ,分析比较不同构成TTCM的方案 ,得到目前已有方案并非最佳 .提出了一种新的构成TTCM方案 ,得到了TTCM误码率的计算公式 .

Base on Euclidean distance (ED), a new method is used to analysis structure of t urbo trellis coded modulation (TTCM) and to calculate bit error rates in this p aper. Maximum free ED is considered as an important criterion for comparing diff erent schemes of TTCM , from which we may conclude that most existing schemes ar e not the best. A new scheme proposed in this paper seems to be an attractive c onstruction for TTCM. The simulation has proved the effectiveness of the propose d new method.
