在中等偏差范围内，研究了无记忆信道上因果无噪声反馈的分组编码。通过一个匡威的，我们表明，反馈并没有改善的亚指数衰减率的最佳错误概率的某一类离散无记忆信道，其中包括对称的，以及加性白色高斯噪声信道受到几乎肯定的功率约束。
Block coding over memoryless channels with causal and noiseless feedback is investigated in the moderate deviations regime. By means of a converse, we show that feedback does not improve the sub-exponential decay rate of the optimal error probability for a certain class of discrete memoryless channels, which includes symmetric ones, as well as the additive white Gaussian noise channel subject to an almost-sure power constraint.
