动作依赖严格因果状态通信

Action Dependent Strictly Causal State Communication

Chiranjib Choudhuri, Urbashi Mitra

摘要:

通信和状态估计的问题被认为是在上下文中的信道与actiondependent状态。给定要传送的消息,发送器选择影响信道状态的形成的动作序列,然后基于状态序列创建信道输入序列。解码器估计信道的一些失真以及解码消息。这种信道的容量失真折衷的特征在于当状态信息在信道编码器处严格因果地可用时的情况。问题设置扩展了[1]的动作依赖框架,并且作为特殊情况恢复了[2],[3],[4]中先前考虑的几个联合通信和估计场景的结果。还考虑了动作也允许依赖于过去观察到的状态(自适应动作)的情况。结果表明,这种自适应行动产生一个改进的能力失真函数。

英文摘要:

The problem of communication and state estimation is considered in the context of channels with actiondependent states. Given the message to be communicated, the transmitter chooses an action sequence that affects the formation of the channel states, and then creates the channel input sequence based on the state sequence. The decoder estimates the channel to some distortion as well as decodes the message. The capacity-distortion tradeoff of such a channel is characterized for the case when the state information is available strictly causally at the channel encoder. The problem setting extends the action dependent framework of [1] and as a special case recovers the results of few previously considered joint communication and estimation scenarios in [2], [3], [4]. The scenario when the action is also allowed to depend on the past observed states (adaptive action) is also considered. It is shown that such adaptive action yields an improved capacity-distortion function.
