Performance of cooperation strategies for a diamond relay network
Feng Xue, Sumeet Sandhu · 2007
How cooperation schemes improve end-to-end information rate of a two-relay half-duplex diamond network is studied. The signaling is close-loop in that the channel information is available at every node. Schemes such as amplify-forward, decode-forward, decode-beamforming, compress-forward, etc., are proposed and characterized for the diamond network. Furthermore, a cut-set upper bound is characterized by a linear programming optimization. How the strategies perform in a fading environment under IEEE 802.16 Erceg model is also plotted, and key observations are presented.
