Optimizing Training-Based Transmission for Correlated MIMO Systems with Hybrid Feedback
Abstract--In this paper, we consider multiple-input multipleoutput (MIMO) communication systems with combined channel covariance feedback (CCF) and channel gain feedback (CGF), her...

On the Optimal Receiver Activation Function for Distance-Based Geographic Transmissions
In wireless networks, the channels are often subject to random variations that limit the reliability of communications between any two radios. Geographic transmission strategies ca...

On Threshold BDDs and the Optimal Variable Ordering Problem
Abstract. Many combinatorial optimization problems can be formulated as 0/1 integer programs (0/1 IPs). The investigation of the structure of these problems raises the following ta...

Connections in Networks: Hardness of Feasibility Versus Optimality
We study the complexity of combinatorial problems that consist of competing infeasibility and optimization components. In particular, we investigate the complexity of the connectio...
