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.

对干扰信道行为的理解的最新进展带来了有价值的见解：首先，已经发现离散信令在存在干扰的情况下具有切实的好处，尤其是当人们不希望对干扰信号进行解码时，即干扰被视为噪声，其次，作为干扰链路增益函数的干扰信道容量现在被理解为高度不规则的，即非单调和不连续的。这项工作以综合和跨学科的方式解决了这两个问题：它利用离散信令通过在离散调制下开发互信息的下界并将干扰视为噪声来接近干扰信道的容量，受中断集的影响，并解决了使用液态金属可重构天线链接增益的敏感性问题，以避免上述中断集。模拟说明了我们方法的有效性。
