On the Achievable Diversity-Multiplexing Tradeoff in Interference Channels

Free registration required

Executive Summary

The authors analyze two-user single-antenna fading interference channels with perfect receive Channel State Information (CSI) and no transmit CSI. For the case of very strong interference, they prove that decoding interference while treating the intended signal as noise, subtracting the result out, and then decoding the desired signal, a process known as "Stripping", achieves the Diversity-Multiplexing Tradeoff (DMT) outer bound derived in Akuiyibo and Leveque, Int. Zurich Seminar on Commun., 2008. The proof is constructive in the sense that it provides corresponding code design criteria for DMT optimality.
