Multiple Repeater Placement for Assisting Long-Range LOS MIMO Links
— A wireless MIMO link is considered in a LOS configuration with multiple SISO wireless repeaters assisting. A theoretical analysis is presented in which repeater positions are c...

Distributed subgradient projection algorithm for convex optimization
—We consider constrained minimization of a sum of convex functions over a convex and compact set, when each component function is known only to a specific agent in a timevarying...

A multiplicative weight perturbation scheme for distributed beamforming in wireless relay networks with 1-bit feedback
This paper focuses on perturbation-based distributed beamforming with 1-bit feedback for wireless amplify-and-forward relay networks. We propose to use multiplicative perturbation...

Protocols and Resource Allocation for the Two-Way Relay Channel with Half-Duplex Terminals
—The two-way relay channel (TWRC) describes the communication between two terminals sharing a common relay. In this work we compare different protocols for the TWRC with a half-d...
