On the Optimality of Treating Interference as Noise: Compound Interference Networks
Chunhua Geng, Syed A. Jafar
In a K-user Gaussian interference channel, it has been shown by Geng et al. that if for each user the desired signal strength is no less than the sum of the strengths of the strong…
The DoF of the Asymmetric MIMO Interference Channel with Square Direct Link Channel Matrices
Tang Liu, Daniela Tuninetti, Syed A. Jafar
This paper studies the sum Degrees of Freedom (DoF) of -user {\em asymmetric} MIMO Interference Channel (IC) with square direct link channel matrices, that is, the -th transm…
Rank Matching for Multihop Multiflow
Hua Sun, Sundar R. Krishnamurthy, Syed A. Jafar
We study the degrees of freedom (DoF) of the layered 2 X 2 X 2 MIMO interference channel where each node is equipped with arbitrary number of antennas, the channels between the nod…
Genie Chains: Exploring Outer Bounds on the Degrees of Freedom of MIMO Interference Networks
Chenwei Wang, Hua Sun, Syed A. Jafar
In this paper, we propose a novel genie chains approach to obtain information theoretic degrees of freedom (DoF) outer bounds for MIMO wireless interference networks. This new appr…
Aligned Image Sets under Channel Uncertainty: Settling a Conjecture by Lapidoth, Shamai and Wigger on the Collapse of Degrees of Freedom under Finite Precision CSIT
Arash Gholami Davoodi, Syed A. Jafar
A conjecture made by Lapidoth, Shamai and Wigger at Allerton 2005 (also an open problem presented at ITA 2006) states that the DoF of a 2 user broadcast channel, where the transmit…
On the Vector Broadcast Channel with Alternating CSIT: A Topological Perspective
Jinyuan Chen, Petros Elia, Syed Ali Jafar
In many wireless networks, link strengths are affected by many topological factors such as different distances, shadowing and inter-cell interference, thus resulting in some links…
