This paper considers the asymptotic behavior of the outage probability of a two-source block-fading single-antenna Gaussian interference channel in the high-SNR regime by means of the diversity-multiplexing tradeoff. A general setting where the user rates and the average channel gains are not restricted to be symmetric is investigated. This asymmetric scenario allows to analyze networks with “mixed”...
This paper considers the asymptotic behavior of the outage probability of two-source block-fading SISO interference channels (IFC) in the high-SNR regime. As opposed to previous works, we characterize the diversity, i.e., exponent of the outage probability, for asymmetric networks, that is to say, for arbitrary signal and interference levels at the receivers. Our result is not just a simple extension...
This work analyzes a particular achievable region for Gaussian interference channels (IFC) derived from the general Han-Kobayashi region. By reformulating the Han-Kobayashi achievable region as the sum of two sets, we characterize the maximum achievable sum-rate with Gaussian inputs and without time-sharing in closed from for any channel parameter. We then show that the computed sum-rate meets the...
