针对典型的二用户对称高斯干扰信道，研究了将干扰视为噪声的局限性。提出了一种两步法，用于在高信噪比（SNR）范围内找到近似最佳的输入分布。首先，为 Avestimehr-Diggavi-Tse (ADT) 线性确定性模型找到近似且精确的最佳输入分布。然后，这些分布被系统地转换为高斯模型，我们证明该模型可以将总容量达到 O(log log(SNR)) 以内。
The limits of treating interference as noise are studied for the canonical two-user symmetric Gaussian interference channel. A two-step approach is proposed for finding approximately optimal input distributions in the high signal-to-noise ratio (SNR) regime. First, approximately and precisely optimal input distributions are found for the Avestimehr-Diggavi-Tse (ADT) linear deterministic model. These distributions are then translated, systematically, into Gaussian models, which we show can achieve the sum capacity to within O(log log(SNR)).
