编码器状态信息不对称的无记忆多址信道容量

On the Capacity of Memoryless Finite-State Multiple-Access Channels with Asymmetric State Information at the Encoders

Giacomo Como, Serdar Yüksel

摘要:

当信道状态过程为独立同分布序列时,发送端可获得部分(量化)状态信息,而接收端可获得完整的信道状态信息,本文给出了有限状态多址信道容量区域的单字母特征。假设部分信道状态信息在编码器处是不对称的。作为主要贡献,给出了一个紧逆编码定理。当信道状态有记忆的情况下,相关的困难进行了讨论,并连接到分散随机控制理论。

英文摘要:

A single-letter characterization is provided for the capacity region of finite-state multiple-access channels, when the channel state process is an independent and identically distributed sequence, the transmitters have access to partial (quantized) state information, and complete channel state information is available at the receiver. The partial channel state information is assumed to be asymmetric at the encoders. As a main contribution, a tight converse coding theorem is presented. The difficulties associated with the case when the channel state has memory are discussed and connections to decentralized stochastic control theory are presented.
