Joint Linear Processing for an Amplify-and-Forward MIMO Relay Channel with Imperfect Channel State Information
The problem of jointly optimizing the source precoder, relay transceiver, and destination equalizer has been considered in this paper for a multiple-input-multiple-output (MIMO) amplify-and-forward (AF) relay channel, where the channel estimates of all links are assumed to be imperfect. The considered joint optimization problem is nonconvex and does not offer closed-form solutions. However, it ...
متن کاملImproved MAP Signal Detection for Amplify-and-Forward Relay Networks with Imperfect Channel State Information
In amplify-and-forward wireless relay networks, channel state information is required at the destination for signal detection when coherent distributed space-time coding is performed at the relays. We consider in this paper signal detection in the case of imperfect partial channel knowledge at the destination. For the case of maximum a posteriori signal detection, we propose a modified detector...
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 کاملRobust MIMO Relay Precoder Design for Multiple Operator One-Way Relaying with Imperfect Channel State Information
In this paper, we propose a robust relay precoder in the multiple operator relay sharing system, where multiple base stations transmit to their target user terminals simultaneously with the assistance of an amplify-and-forward relay. The base stations and the user terminals are equipped with single antennas while the relay employs multiple antennas. The channel state information at the relay is...
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...
