Joint Source-Relay Precoding with MMSE-based Interference Suppression in two-way MIMO Amplify and Forward Relays
In this paper, we consider a two-way multiple input multiple output (MIMO) Amplify-and-Forward (AF) relay system, where interference is observed at the relay node during the multiple access (MAC) phase. For such a scenario, two new joint source-relay precoding algorithms with interference suppression are proposed and their performance analyzed through simulation results. These linear minimum me...
متن کاملJoint 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...
متن کاملMMSE-based joint source and relay optimization for interference MIMO relay systems
In this paper, we investigate the transceiver design for amplify-and-forward (AF) interference multiple-input multiple-output (MIMO) relay communication systems when the direct links between the source and destination nodes are taken into consideration. The minimum mean-squared error (MMSE) of the signal waveform estimation at the destination nodes is chosen as the design criterion to optimize ...
متن کاملRobust MMSE Precoding for Multiuser MIMO Relay Systems using Switched Relaying and Side Information
This study proposes a novel precoding scheme for multiuser multiple-input multiple-output (MIMO) relay systems in the presence of imperfect channel state information (CSI). The base station (BS) and the MIMO relay station (RS) are both equipped with the same codebook of unitary matrices. According to each element of the codebook, we create a latent precoding matrix pair, namely a BS precoding m...
متن کاملA Non-Alternating Algorithm for Joint BS-RS Precoding Design in Two-Way Relay Systems
Cooperative relay systems have become an active area of research during recent years since they help cellular networks to enhance data rate and coverage. In this paper we develop a method to jointly optimize precoding matrices for amplify-and-forward relay station and base station. Our objective is to increase max–min SINR fairness within co-channel users in a cell. The main achievement of this...
