Degrees of freedom in vector interference channels
Degrees of freedom in vector interference channels
This paper continues the Wu-Shamai-Verdú program [1] on characterizing the degrees of freedom (DoF) of interference channels (ICs) through Rényi information dimension. Concretely, we find a general formula for the DoF of vector ICs, encompassing multiple-input multiple-output (MIMO) ICs, time- and/or frequency-selective ICs, and combinations thereof, as well as constant …
