论文摘要
我们在上述纸张的III-B中纠正错误。校正与对主解码器的输入的联合分布有关,该分布与主解码器的代码格子中的分支相对应。请注意,就与单个代码符号相对应的输入的分布而言,第三节中的结果是正确的。我们已经注意到,命题12中的Alpha(命题14中的Beta)具有另一个含义,这使得可以得出与整个分支相对应的输入的联合分布。更正是基于这个重要的观察结果。
We correct errors in Section III-B of the above-titled paper. The corrections are related to the joint distribution of the inputs to the main decoder which corresponds to a branch in the code trellis for the main decoder. Note that as far as the distribution of the input corresponding to a single code symbol is concerned, the results in Section III-B are correct. We have noticed that alpha in Proposition 12 (beta in Proposition 14) has another meaning, which has made it possible to derive the joint distribution of the inputs corresponding to the whole branch. Corrections are based on this important observation.
