| 摘 要： | 提出了一种用欧氏距离分析并行级联网格编码调制（ＴＴＣＭ）的构成及误码率的方法，以最大自由欧氏距离（ＭＦＥＤ）为依据，分析得到目前已有几种构成方案产非最佳ＴＴＣ邮一种构成最佳ＴＴＣＭ的方案，得到了ＴＴＣＭ误码率的计算公式，并地结果进行了仿真，证明了这种的有效性。

| Abstract: | Based on Euclidean distance(ED), a new method is proposed, which can be used to analyse structure of parallel concatenated trellis coded modulation(TTCM) and computer bit error rates. Maximum free ED is made as a criterion, and the conclusion is drawn that past schemes of constructing TTCM are not the best. One best scheme and relaxation of bit error rate is obtained, and the conclusion is simulated and correctness of the method is also proved . |
