In this paper, we study a relay-aided multiuser amplify-and-forward relaying system where a
multi-antenna base station (BS) transmits downlink to multiple single-antenna mobile …

We consider efficient communications over the multiple-input multiple-output (MIMO)
multiway relay channel (mRC) with full data exchange, where each user, equipped with …

Lattice reduction (LR) has been used widely in conventional multiple-input multiple-output
(MIMO) systems to enhance the performance. However, LR is hard to be applied to the relay …

We design a scheme of precoding matrices for two-way multiuser relay systems, where a
multiantenna relay station (RS) operating in an amplify-and-forward model simultaneously …

In this paper, we consider the transceiver and relay design for the multiple-input multiple-
output (MIMO) cellular two-way relay channel (cTWRC), where a multi-antenna base station …

Two-way relaying can improve spectral efficiency in two-user cooperative communications. It
also has great potential in multiuser systems. A major problem of designing a multiuser two …

Two-way relaying has demonstrated significant gain in spectral efficiency by applying
network coding when a pair of source nodes exchange information via a relay node. This …

In this paper, an iterative precoding method is proposed, which successively in turn
optimizes the precoding matrix at base station or relay station for suppressing the multiuser …

This paper 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 …

In this work, we propose a linear base station (BS) precoding strategy based on switched
relaying (SR) processing for downlink multiuser multiple-input multiple-output (MIMO) relay …
