研究了全双工中继的两用户高斯干扰信道。通过使用精灵辅助方法，得出了此设置中可实现的总速率的两个新上限。在某些条件下，这些上限比先前已知的界限更严格。此外，还提出了该设置的传输策略。该策略利用以下元素：在源处将块马尔可夫编码与 Han-Kobayashi 方案相结合，在中继处进行解码和转发，以及在接收器处进行 Willems 后向解码。在某些情况下，该方案被证明可以在有限的间隙内达到我们的上限。
The two user Gaussian interference channel with a full-duplex relay is studied. By using genie aided approaches, two new upper bounds on the achievable sum-rate in this setup are derived. These upper bounds are shown to be tighter than previously known bounds under some conditions. Moreover, a transmit strategy for this setup is proposed. This strategy utilizes the following elements: Block Markov encoding combined with a Han-Kobayashi scheme at the sources, decode and forward at the relay, and Willems' backward decoding at the receivers. This scheme is shown to achieve within a finite gap our upper bounds in certain cases.
