AI 中文摘要
我们研究唯一可解码码对的最大和速率。对一种补集粘合构造进行加权细化,得到长度为672的显式码,其和速率超过1.318639029203。结合条件熵估计与合理连续极限的迭代投影论证,给出了1.480063425539的上界。
英文摘要
We study the maximum sum rate of uniquely decodable code pairs. A weighted refinement of a complement-gluing construction yields an explicit code of length 672 and sum rate exceeding $1.318639029203$. An iterated projection argument, combined with a conditional entropy estimate and a justified continuous limit, gives an upper bound of $1.480063425539$.
