在这项研究中，作者建立了三种高斯多址信道（mac）的可实现速率和容量区域，这些信道在发射机处具有部分（估计或感知版本）和非因果已知的侧信息（SI）。实际上，作者表明，对于部分SI的高斯MACs，晶格策略是最优的，与philosophy - zamir研究的具有完全SI的高斯MACs相同。速率和容量区域，虽然显示了SI中的偏好降低了可实现的速率，但直接将philosofzamir速率区域以及Gueguen-Sayrac工作和Costa定理间接地作为特殊情况包含在内。
In this study, the authors establish achievable rate and capacity regions for three kinds of Gaussian multiple access channels (MACs) with side information (SI) partially (estimated or sensed version) and non-causally known at the transmitters. Actually, the authors show that the lattice strategy is optimal for Gaussian MACs with partial SI, the same as it is for Gaussian MACs with full SI studied by Philosof–Zamir. The rate and capacity regions, while showing that partiality in SI reduces the achievable rates, subsumes directly the Philosof–Zamir rate regions and also the Gueguen–Sayrac work and the Costa theorem indirectly as special cases.
