Joint Transceiver Design for Amplify-and-Forward Multiuser MIMO Relay Communication Systems with Source-Destination Links

—In this paper, we generalize the iterative algorithms proposed by Khandaker to amplify-and-forward multiuser Multiple-Input Multiple-Output (MIMO) relay communication systems with the source-destination links. Compared with the conventional algorithms, where the source-destination links are ignored, the evolved Tri-Step method and Bi-Step method are derived for the new system model with the s...

Robust Multibranch Tomlinson-Harashima Precoding Design in Amplify-and-Forward MIMO Relay Systems

This paper proposes the design of robust transceivers with Tomlinson-Harashima precoding (THP) for multipleinput multiple-output (MIMO) relay systems with amplify-andforward (AF) protocols based on a multi-branch (MB) strategy. The MB strategy employs successive interference cancellation (SIC) on several parallel branches which are equipped with different ordering patterns so that each branch p...

Joint Source and Relay Precoding Design for One-Way Full-Duplex MIMO Relaying Systems

In this paper we address the sum rate maximization problem for a one-way amplify-and-forward relaying system with a full-duplex relay. This optimization problem which requires the joint source and relay precoding design is in general nonconvex. We propose different convex optimization based suboptimal schemes for different system settings. Moreover, we derive a gradient projection based algorit...

Multiuser Full-Duplex Communication

The inevitable high bandwidth requirement in the future cellular network has made researchers to come up with revolutionary ideas in recent times. One such idea is the introduction of full-duplex (FD) communication. A FD systems make the simultaneous in-band transceiving feasible, i.e, simultaneous uplink and downlink operation using the same spectrum resources. In recent years, extensive work ...
