This paper proposes a low complexity protocol that preserves full diversity in multiuser
amplify-and-forward relay networks with NS antennas at the source, NR antennas at the …

Cooperative communication has the potential of providing better throughput and reliability to
wireless systems when compared with direct communication. To realise the potential gain, it …

In this letter, we propose a beamforming and combining scheme for a two-way amplify-and-
forward (AF) multiple-input multiple-output (MIMO) relay network. An approximate …

In this paper, we analyze the performance of a full-duplex (FD) amplify-and-forward (AF)
relay system under various cases of relaying gains and channel state information conditions …

In this letter, we investigate the effect of feedback delay on the performance of a dual-hop
amplify-and-forward (AF) relay network with beamforming in the presence of multiple …

The performance of a dual-hop fixed gain amplify-and-forward multiple-input multiple-output
relay network is analyzed. Both the relay station and the mobile station are subjected to …

In this paper, we investigate the effects of line-of-sight (LoS) path and opportunistic
scheduling (OS) on dualhop energy harvesting (EH) relay systems, where the LoS path …

Orthogonal frequency-division multiplexing with index modulation (OFDM-IM) has recently
attracted many researchers' attention due to its superior spectrum efficiency and reliability …

In this letter, we develop a unified framework for the ergodic capacity of dual-hop multiple
antenna amplify-and-forward (AF) relaying systems employing transmit beamforming and …

Cooperative communication is a precious approach to overcome the interference of
multiuser communication and increase data rate of communication system. Many papers are …
