Using Limited Feedback in Power Allocation Design for a Two-Hop Relay OFDM System
In this paper, we study power allocation (PA) in a single-relay OFDM system with limited feedback. We propose a PA scheme that uses a codebook of quantized PA vectors designed offl...

Cooperative MIMO-beamforming for multiuser relay networks
In this paper, we develop a beamforming algorithm for multiuser MIMO-relaying wireless systems. We consider a relaying scenario with multiple sources transmitting to one or more d...
