Capacity Bounds for the Gaussian Interference Channel
Abstract-- The capacity region of the two-user Gaussian Interference Channel (IC) is studied. Two classes of channels are considered: weak and mixed Gaussian IC. For the weak Gauss...

Effects of Imperfect Channel State Information on Achievable Rates of Precoded Multi-User MIMO Broadcast Channels with Limited F
—We consider multi-user MIMO broadcast channels with limited feedback. A recently proposed linear precoding technique, regularized block diagonalization (RBD), is used to mitigat...

Degrees of Freedom of the MIMO X Channel
— We provide achievability as well as converse results for the degrees of freedom region of a MIMO X channel, i.e., a system with two transmitters, two receivers, each equipped w...

Feedback Capacity of the Gaussian Interference Channel to within 2 Bits
We characterize the capacity region to within 2 bits/s/Hz and the symmetric capacity to within 1 bit/s/Hz for the two-user Gaussian interference channel (IC) with feedback. We dev...

Distributed Adaptation of Quantized Feedback for Downlink Network MIMO Systems
Abstract—This paper focuses on quantized channel state information (CSI) feedback for downlink network MIMO systems. Specifically, we propose to quantize and feedback the CSI of...
