本文研究了在二进制输入信道下，带无噪声反馈的变长编码问题。提出了一种确定性顺序编码方案，并示出达到最佳的错误指数的任何二进制输入信道的容量是由均匀的输入分布。所提出的方案是确定性的，只有一个阶段的操作，在对比所有以前的编码方案，实现最佳的错误指数。
This paper considers the problem of variable-length coding over a binary-input channel with noiseless feedback. A deterministic sequential coding scheme is proposed and shown to attain the optimal error exponent for any binary-input channel whose capacity is achieved by the uniform input distribution. The proposed scheme is deterministic and has only one phase of operation, in contrast to all previous coding schemes that achieve the optimal error exponent.
