带噪声反馈实时的通信系统

On Real-Time Communication Systems with Noisy Feedback

Aditya Mahajan, Demosthenis Teneketzis

摘要:

我们考虑一个实时的【形】通信系统的噪声反馈组成的马尔可夫源,前向和后向离散无记忆信道,和一个接收机与有限的记忆。我们的目标是设计一个最佳的通信策略(即,编码,解码和内存更新策略),以尽量减少总的预期失真在有限的地平线。我们提出了一个顺序分解的问题,这导致在一组嵌套的最优性方程,以确定最佳的通信策略。这提供了一个系统的方法来确定全局最优的联合信源信道编码和解码策略的实时的【形】通信系统与噪声反馈。

英文摘要:

We consider a real-time communication system with noisy feedback consisting of a Markov source, a forward and a backward discrete memoryless channels, and a receiver with finite memory. The objective is to design an optimal communication strategy (that is, encoding, decoding, and memory update strategies) to minimize the total expected distortion over a finite horizon. We present a sequential decomposition for the problem, which results in a set of nested optimality equations to determine optimal communication strategies. This provides a systematic methodology to determine globally optimal joint source-channel encoding and decoding strategies for real-time communication systems with noisy feedback.
