Optimal Relay Assignment and Power Allocation in Selection Based Cooperative Cellular Networks
—We consider a system with a single base station communicating with multiple users over orthogonal channels while being assisted by multiple relays. Several recent works have sug...

Characterization of Relay Channels Using the Bhattacharyya Parameter
—Relay systems have large and complex parameter spaces, which makes it difficult to determine the parameter region where the system achieves a given performance criterion, such ...

The Art of Signaling: Fifty Years of Coding Theory
—In 1948 Shannon developed fundamental limits on the efficiency of communication over noisy channels. The coding theorem asserts that there are block codes with code rates arbit...

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...
