在本文中，一个单一的字母特征的有限状态多址接入信道（MAC）的容量区域与部分合作编码器的推导。这里的部分合作是指编码器通过有限容量链路相互通信。信道状态被假定为由马尔可夫过程。在接收器处假设全信道状态信息（CSI），而在发射器处仅延迟的CSI可用。容量区域是通过首先解决有限状态多址信道的情况下，共同的消息，使用速率分裂，复用和同时解码，以建立可扩展性。共同的消息结果，然后用于推导部分合作编码器的情况下的容量区域。最后，我们应用这个结果，以获得有限状态高斯MAC部分合作编码器的容量区域。
In this paper, a single-letter characterization for the capacity region of finite-state multiple access channels (MACs) with partially cooperative encoders is derived. Partial cooperation here is in the sense that the encoders communicate with each other through finite-capacity links. The channel states are assumed to be governed by a Markov processes. Full channel state information (CSI) is assumed at the receiver, while only delayed CSI is available at transmitters. The capacity region is derived by first solving the case of finite-state multiple access channels with common message, using rate splitting, multiplexing and simultaneous decoding in order to establish the achievability. The common message result is then used to derive the capacity region of the partially cooperative encoders case. Finally, we apply this result in order to obtain the capacity region for a finite-state Gaussian MAC with partially cooperative encoders.
