标题： Source-Channel Coding for the Multiple-Access Relay Channel

摘要： 这项工作考虑了在多接入中继信道（MARC）和多接入广播中继信道（MABRC）上一般相关源的可靠传输。 在MARC中只有目的地对源的重建感兴趣，而在MABRC中中继和目的地都希望重建源。 我们假设中继和目的地都有相关的辅助信息。 我们基于操作分离找到了可靠通信的充分条件，以及可实现的源信道速率的必要条件。 对于在衰落高斯MARC和MABRC上传输的相关源，我们找到了信息分离最优的条件。 显示英文摘要

摘要： This work considers reliable transmission of general correlated sources over the multiple-access relay channel (MARC) and the multiple-access broadcast relay channel (MABRC). In MARCs only the destination is interested in a reconstruction of the sources, while in MABRCs both the relay and the destination want to reconstruct the sources. We assume that both the relay and the destination have correlated side information. We find sufficient conditions for reliable communication based on operational separation, as well as necessary conditions on the achievable source-channel rate. For correlated sources transmitted over fading Gaussian MARCs and MABRCs we find conditions under which informational separation is optimal.
