Query: Diversity-Multiplexing tradeoff of the Two-User Interference Channel   Diversity-Multiplexing tradeoff (DMT) is a coarse high SNR approximation of
the fundamental tradeoff between data rate and reliability in a slow fading
channel. In this paper, we characterize the fundamental DMT of the two user
single antenna Gaussian interference channel. We show that the class of
multilevel superposition coding schemes universally achieves (for all fading
statistics) the DMT for the two-user interference channel. For the special case
of symmetric DMT, when the two users have identical rate and diversity gain
requirements, we characterize the DMT achieved by the Han-Kobayashi scheme,
which corresponds to two level superposition coding.
