On the design of Amplify-and-Forward MIMO-OFDM Relay Systems with QoS requirements
In this letter, we focus on the design of linear and non-linear architectures in amplify-and-forward multiple-input multiple-output orthogonal frequency-division multiplexing relay networks in which different types of services are supported. The goal is to jointly optimize the processing matrices so as to minimize the total power consumption while satisfying the quality-of-service requirements ...
متن کاملEfficient Antenna Selection for Amplify-and-Forward Two-Way MIMO Relay Systems
In this letter, we propose an efficient relay antenna selection algorithm for the amplify and forward (AF) two-way multipleinput multiple-output (MIMO) relay systems with analogue network coding (ANC). The proposed algorithm greedily selects the additional receivetransmit antenna pair that provides the maximum sum-rate. An iterative computation method is also designed to evaluate the sum-rate e...
متن کاملRobust 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...
متن کاملJoint 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...
متن کاملOn the Performance of Cooperative Amplify-and-Forward Relay Networks
This paper provides a general analysis of cooperative amplify-and-forward relay networks and gives a unified and comparative view of various proposed systems. The studied cooperative relay networks offer spatial diversity gains that conventional multi-antenna systems often fail to achieve due to limitations of the feasible number of antennas per terminal and correlated propagation. We first pre...
