Codebook-Based Opportunistic Interference Alignment
Hyun Jong Yang, Bang Chul Jung, Won-Yong Shin +1
Opportunistic interference alignment (OIA) asymptotically achieves the optimal degrees-of-freedom (DoF) in interfering multiple-access channels (IMACs) in a distributed fashion, as…
Opportunistic Interference Alignment for MIMO Interfering Multiple-Access Channels
Hyun Jong Yang, Won-Yong Shin, Bang Chul Jung +1
We consider the -cell multiple-input multiple-output (MIMO) interfering multiple-access channel (IMAC) with time-invariant channel coefficients, where each cell consists of a ba…
Achievable and Crystallized Rate Regions of the Interference Channel with Interference as Noise
Mohamad Awad Charafeddine, Aydin Sezgin, Zhu Han +1
The interference channel achievable rate region is presented when the interference is treated as noise. The formulation starts with the 2-user channel, and then extends the results…
On Gaussian Multiple Access Channels with Interference: Achievable Rates and Upper Bounds
Anas Chaaban, Aydin Sezgin, Bernd Bandemer +1
We study the interaction between two interfering Gaussian 2-user multiple access channels. The capacity region is characterized under mixed strong--extremely strong interference an…
Crystallized Rates Region of the Interference Channel via Correlated Equilibrium with Interference as Noise
Mohamad Charafeddine, Zhu Han, Arogyaswami Paulraj +1
Treating the interference as noise in the n-user interference channel, the paper describes a novel approach to the rates region, composed by the time-sharing convex hull of 2^n-1 c…
Rate Region Frontiers for n-user Interference Channel with Interference as Noise
Mohamad Charafeddine, Aydin Sezgin, Arogyaswami Paulraj
This paper presents the achievable rate region frontiers for the n-user interference channel when there is no cooperation at the transmit nor at the receive side. The receiver is a…
On the ergodic sum-rate performance of CDD in multi-user systems
Aydin Sezgin, Mohamad Charafeddine, Arogyaswami Paulraj
The main focus of space-time coding design and analysis for MIMO systems has been so far focused on single-user systems. For single-user systems, transmit diversity schemes suffer…
Power-Bandwidth Tradeoff in Dense Multi-Antenna Relay Networks
Ozgur Oyman, Arogyaswami J. Paulraj
We consider a dense fading multi-user network with multiple active multi-antenna source-destination pair terminals communicating simultaneously through a large common set of mu…
