Performance Analysis of Hop-by-Hop Beamforming and Combining in DF MIMO Relay System over Nakagami-m Fading Channels

In this paper, we study hop-by-hop beamforming and combining in a decode-and-forward (DF) multiple-input multiple-output (MIMO) relay network, with two antennas at each node, over Nakagami-m fading channels. We derive a closed-form expression of the approximate average bit error rate of the consider...

Zusammenfassung:	In this paper, we study hop-by-hop beamforming and combining in a decode-and-forward (DF) multiple-input multiple-output (MIMO) relay network, with two antennas at each node, over Nakagami-m fading channels. We derive a closed-form expression of the approximate average bit error rate of the considered cooperative scheme with M-ary phase shift keying constellation. In addition, analytical outage probability and diversity order of the considered DF MIMO relay system are also obtained.
