Given a multiple-antenna source and a multiple-antenna destination, a multiple-antenna
relay between the source and the destination is desirable under useful circumstances. A non …

This paper deals with the design of nonregenerative relaying transceivers in cooperative
systems where channel state information (CSI) is available at the relay station. The …

We consider a two-hop MIMO-OFDM communication scheme with a source, an amplify-and-
forward relay, and a destination. We examine the possibilities of power allocation (PA) over …

In this paper, a novel relaying strategy that uses multiple-input multiple-output (MIMO) fixed
relays with linear processing to support multiuser transmission in cellular networks is …

We consider the problem of beamforming codebook design for limited feedback half-duplex
multiple-input multiple output (MIMO) amplify-and-forward (AF) relay system. In the first part …

Amplify-and-Forward (AF) is a simple but effective relaying concept for multihop networks
that combines transparency regarding modulation format and coding scheme with ease of …

Two new precoding schemes based on the minimum mean-square error (MMSE) criterion
for amplify-and-forward MIMO relay networks with quality-of-service (QoS) requirements are …

This paper studies the precoder design for a 3-node non-generative MIMO relay channel,
taking the direct link transmission into consideration. We first look into the scenario where …

This paper investigates achievable information rate and relay precoder design of multiple-
input-multiple-output (MIMO) amplify-and-forward (AF) relay networks under imperfect …

This letter proposes a method for channel state information (CSI) estimation in a wireless
relay network, which consists of a base station (BS), a relay station (RS), and a mobile …
