The authors establish the high SNR diversity-multiplexing tradeoff of the fading interference channel, for a general interference level and under the assumption that transmitters and receivers are equipped with a single antenna each. Considered initially by Shannon in, the interference channel describes the shared medium in which two or more transmitter-receiver pairs wishing to communicate reliably, interfere with each other. Although the general capacity region remains unknown in the simplest scenario with two communicating pairs, a recent result by Etkin, Tse and Wang has shed light on the particular case where both interference and noise are additive, and noise is Gaussian.
