On Cognitive Interference Networks
— We study the high-power asymptotic behavior of the sum-rate capacity of multi-user interference networks with an equal number of transmitters and receivers. We assume that each...

Optimal Order of Decoding for Max-Min Fairness in K-User Memoryless Interference Channels
A K-user memoryless interference channel is considered where each receiver sequentially decodes the data of a subset of transmitters before it decodes the data of the designated t...

Broadcast Cooperation Strategies for Two Colocated Users
This work considers the problem of communication from a single transmitter, over a network with colocated users, through an independent block Rayleigh fading channel. The colocati...

On the Capacity of Fading MIMO Broadcast Channels with Imperfect Transmitter Side-Information
A fading broadcast channel is considered where the transmitter employs two antennas and each of the two receivers employs a single receive antenna. It is demonstrated that even if...

Capacity of Block-Memoryless Channels with Causal Channel Side Information
The capacity of a time-varying block-memoryless channel in which the transmitter and the receiver have access to (possibly different) noisy causal channel side information (CSI) i...

High-SIR Transmission Capacity of Wireless Networks with General Fading and Node Distribution
In many wireless systems, interference is the main performance-limiting factor, and is primarily dictated by the locations of concurrent transmitters. In many earlier works, the l...

Degrees of Freedom of the MIMO Interference Channel with Cooperation and Cognition
In this paper, we explore the benefits, from the perspective of degrees of freedom (DOF), of user cooperation and cognitive message sharing for a two-user multiple-input-multiple-...

CSMA/CN: carrier sense multiple access with collision notification
A wireless transmitter learns of a packet loss, infers collision, only after completing the entire transmission. If the transmitter could detect the collision early (such as with ...

Interference-constrained wireless coverage in a protocol model
We present an efficient algorithm to compute the coverage map of a given set of transmitters under interference constraints. That is, we compute the set of points that lie within ...

Multiuser MIMO Downlink Transmission Over Time-Varying Channels
—— The performance of multiuser MIMO downlink systems with block diagonalization (BD) relies on the channel state information (CSI) at the transmitter to a great extent. For ti...
