我们考虑通过中继/处理器站互连的串联二进制对称通道可靠地传输一位信息的问题。在我们的设置中，继电器是瞬时的，因为它的输出允许因果关系取决于先前接收到的噪声位。对于该模型，我们通过设计良好的中继方案，研究了当使用 n 个同步信道使用中继一位信息时，平均错误概率的最佳指数衰减率。
We consider the problem of transmitting reliably one bit of information across a tandem of binary symmetric channels interconnected by a relay/processor station. In our setting, the relay is instantaneous in the sense that its outputs are allowed to causally depend on previous received noisy bits. For this model, we investigate the optimal exponential decay rate of the average probability of error, when relaying one bit of information using n synchronous channel uses, by devising good relaying schemes.
