In this paper, we consider the joint design of precoding matrices at both the source and relay nodes in a multi-relay system based on perfect and imperfect channel information, and propose the novel relay selection scheme based on log-likelihood ratio (LLR). Moreover, the symbol error rate (SER) for relay selection system based on proposed scheme is analyzed. At first, we design the combined precoding matrices based on respectively the maximum signal-to-noise ratio (SNR) with perfect channel…

A new scheme of limited feedback joint effective relay selection and beamforming vector design is proposed, which uses a new strategy to share channel information between relay and destination and outperforms conventional schemes, while having lower computational complexity and lower feedback delay.

Precoder Design for OSTBC Based AF MIMO Relay System With Channel Uncertainty

This paper derives a simple approximate symbol error rate (SER) expression for the multiple-relay channels with and without relay selection revealing a higher achievable diversity order by using relay selection than its counterpart with fixed relay configuration.

A maximum likelihood (ML) detector at the multiple-antenna relay is used, and it is proved that this decoding rule can achieve full diversity order at themultiple access (MAC) phase of the MABC protocol.

Joint relay selection and cooperative beamforming in two-hop multi-relay decode-and-forward networks

A new beamforming at the relay is proposed that selects the best two among several relays and then the selected relays forward their detected symbols in a common channel to the destination and achieves full diversity order.

Analytical and numerical results reveal that a full diversity of K is reaped by the proposed scheme when the knowledge of CSI is perfect, and OSTC's capacity is remarkably higher than that of the existing schemes based on orthogonal transmission.

A downlink multiple-input multiple-output decode-and-forward relaying network is analyzed by considering Nakagami-$m$ fading as a model for the channel gains and using a joint scheme (JS), which joints the relay selection and the antenna selection at the base station and the selected relay.
