Abstract: © 2015 IEEE. The limits of treating interference as noise are studied for the canonical twouser symmetric Gaussian interference channel. A twostep approach is proposed for finding approximately optimal input distributions in the high signaltonoise ratio (SNR) regime. First, approximately and precisely optimal input distributions are found for the AvestimehrDiggaviTse (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)).
