| 摘 要： | 提出了一种用欧氏距离分析ＴＵＲＢＯ网各编码调制（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２已有方案并非最佳，提出了一种新的构成ＴＴＣＤ）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，仿真结果证明了这种的有效性。

| Abstract: | 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. |
