在理解干扰信道的行为方面的最新进展已经导致了有价值的见解：首先，已经发现离散信令在存在干扰的情况下具有切实的益处，特别是当不希望解码干扰信号时，即，干扰被视为噪声，第二，作为干扰链路增益的函数的干扰信道的容量现在被理解为是高度不规则的，即，非单调和不连续。这项工作解决了这两个问题，在一个综合的和跨学科的方式：它利用离散信令接近干扰信道的容量，通过开发离散调制下的互信息的下限和处理干扰的噪声，受到中断集，并解决了问题的灵敏度与液态金属可重构天线的链路增益，以避免上述中断集。仿真结果表明了该方法的有效性。
Recent progress in the understanding of the behavior of the interference channel has led to valuable insights: first, discrete signaling has been discovered to have tangible benefits in the presence of interference, especially when one does not wish to decode the interfering signal, i.e., the interference is treated as noise, and second, the capacity of the interference channel as a function of the interference link gains is now understood to be highly irregular, i.e., non-monotonic and discontinuous. This work addresses these two issues in an integrated and interdisciplinary manner: it utilizes discrete signaling to approach the capacity of the interference channel by developing lower bounds on the mutual information under discrete modulation and treating interference as noise, subject to an outage set, and addresses the issue of sensitivity to link gains with a liquid metal reconfigurable antenna to avoid the aforementioned outage sets. Simulations illustrate the effectiveness of our approach.
