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...

On Joint Optimization of Source and Relay Precoding Design for MIMO Downlink Channels

This paper investigates the joint precoding optimization for a relay-assisted multi-antenna downlink system. Aiming at multiuser sum capacity maximization, we first propose an iterative optimization algorithm which exploits quadratic programming approaches. Inspired by the results obtained from the iterative optimization algorithm, in order to further reduce the computational complexity, we the...

Joint source and relay optimization for parallel MIMO relay networks

In this article, we study the optimal structure of the source precoding matrix and the relay amplifying matrices for multiple-input multiple-output (MIMO) relay communication systems with parallel relay nodes. Two types of receivers are considered at the destination node: (1) The linear minimal mean-squared error (MMSE) receiver; (2) The nonlinear decision feedback equalizer based on the minima...
