我们考虑具有反馈的二进制对称信道上的通信问题，其中信息序列以因果（可能是随机的）方式可用。我们开发了著名的Horstein方案的实时变体，并提供了其误差概率指数衰减率的分析保证。我们进一步使用该方案稳定了二进制对称信道上的不稳定控制对象，并将分析保证与其经验性能以及与任意可靠码的性能进行了比较。
We consider the problem of communication over the binary symmetric channel with feedback, where the information sequence is made available in a causal, possibly random, fashion. We develop a real-time variant of the renowned Horstein scheme and provide analytical guarantees for its error-probability exponential decay rate. We further use the scheme to stabilize an unstable control plant over a binary symmetric channel and compare the analytical guarantees with its empirical performance as well as with those of anytime-reliable codes.
