在这项研究中，两个用户的离散无记忆多址信道与两个相关的状态，在相应的编码器被认为是非因果关系。每个编码器发送独立于其他编码器的消息，并试图与之合作。考虑合作编码器，假设每个编码器严格因果地接收并找出其他编码器的发送信号，并试图通过发送其消息与其他编码器合作。一个特殊的情况下，也研究了在两个编码器的状态的公共部分是已知的，从而在一个更大的速率区域。对于这两种情况下，可实现的速率区域推导出使用块马尔可夫和Gel'fand-Pinsker编码技术的组合，并建立了外边界。对于第二种情况，高斯模型的可达速率区域推导，并讨论了一些影响的结果。
In this study, a two-user discrete memoryless multiple-access channel with two correlated states known non-causally at the corresponding encoder is considered. Each encoder transmits a message independent of the other encoder's and tries to cooperate with it. To consider cooperative encoders, it is assumed that each encoder strictly-causally receives and finds out the other encoder's transmitted signals and tries to cooperate with the other encoder by transmitting its message. A special case is also studied in which the common part of the states is known at the both encoders, resulting in a larger rate region. For these two scenarios, achievable rate regions are derived using a combination of block-Markov and Gel'fand-Pinsker coding techniques, and outer bounds are also established. For the second scenario, the achievable rate region of the Gaussian model is derived, and some implications of the results are discussed.
