“…As a result, we obtain a higher throughput, a more robust transmission, and/or we can reduce transmission delay. At present, there is an increasing research interest at the physical layer on distributed and cooperative MIMO techniques, as seen in [13] and [32] and references therein. While past and ongoing research on multiantenna technologies has mostly focused on the wireless link layers between an access point such as a base station and a mobile station using collocated antenna sites, in the future, a network level technology like IPRM will be required to provide time-critical control of data streams if multiple antennas are distributed over network nodes.…”

“…It has been shown in [3] and [4] that performing linear processing at the relay node can outperform the conventional AF relaying in a non-regenerative, also known as amplify-and-forward (AF), MIMO relay system. The optimal relay amplifying matrix which maximizes the mutual information (MI) between source and destination is derived in [5].…”

Recently, multiple-input multiple-output (MIMO) relay technique has been received great attention due to its prominent ability to provide broad coverage and enhance the link reliability and spectral efficiency. In this paper, an overview of optimal design for single user and multiuser non-regenerative MIMO relay systems is proposed. We explore some key designs of source node and destination node as well as relay node processing matrices using minimum mean square error (MMSE) criterion under the transmit power constraints. Simulation results compare different methods in terms of the MSE and bit error rate (BER) performance.

“…In [7], the authors analyze the stream signal-to-interference ratio statistic and consider different relay beamforming based on the finite-rate feedback of the channel states. Assuming TomlinsonHarashima precoding at the base station and linear processing at the relay, [8] proposes upper and lower bounds on the achievable sum rate for the multiuser MIMO system with single relay node.…”

In this paper, we consider a dual-hop Multiple Input Multiple Output (MIMO) relay wireless network, in which a source-destination pair both equipped with multiple antennas communicates through a large number of half-duplex amplify-and-forward (AF) relay terminals. Two novel linear beamforming schemes based on the matched filter (MF) and regularized zero-forcing (RZF) precoding techniques are proposed for the MIMO relay system. We focus on the linear process at the relay nodes and design the new relay beamformers by utilizing the channel state information (CSI) of both backward channel and forward channel. The proposed beamforming designs are based on the QR decomposition (QRD) filter at the destination node which performs successive interference cancellation (SIC) to achieve the maximum spatial multiplexing gain. Simulation results demonstrate that the proposed beamformers that fulfil both the intranode array gain and distributed array gain outperform other relaying schemes under different system parameters in terms of the ergodic capacity. Index TermsMIMO relay, beamforming, successive interference cancellation, ergodic capacity.
