Degrees of freedom of the interference channel: A general formula
Abstract
We give aÌý general Ìý formula Ìýfor theÌý degrees ÌýofÌý freedom Ìýof the K-user real additive-noiseÌý interference channel Ìýinvolving maximization of information dimension. Previous results are recovered, and even generalized in certain cases with simplified proofs. Connections to fractal geometry are drawn.
