Network Coherence Time Matters - Aligned Image Sets and the Degrees of Freedom of Interference Networks with Finite Precision CSIT and Perfect CSIR
Arash Gholami Davoodi, Syed Ali Jafar
This work obtains the first bound that is provably sensitive to network coherence time, i.e., coherence time in an interference network where all channels experience the same coher…

Aligned Image Sets and the Generalized Degrees of Freedom of Symmetric MIMO Interference Channel with Partial CSIT
Arash Gholami Davoodi, Syed A. Jafar
The generalized degrees of freedom (GDoF) of the two user symmetric multiple input multiple output (MIMO) interference channel (IC) are characterized as a function of the channel s…

Sum-set Inequalities from Aligned Image Sets: Instruments for Robust GDoF Bounds
Arash Gholami Davoodi, Syed A. Jafar
We present sum-set inequalities specialized to the generalized degrees of freedom (GDoF) framework. These are information theoretic lower bounds on the entropy of bounded density l…
