Abstract：

This　paper　considers　two　hop　MIMO-OFDM　AF　relaying　systems　with　separate　power　constraint　at　source　and　relay.　In　order　to　maximize　the　system　capacity,　the　adaptive　transmission　is　realized　by　two　steps　of　beamforming　with　equal　power　and　then　power　allocation.　For　the　limited　feedback　scenario,　we　utilize　the　Grassmannian　beamforming　codebooks　as　the　source　and　relay　beamforming　codebooks　and　design　the　power　allocation　codebook　based　on　Lloyd＇s　algorithm.　Simulations　show　the　advantages　of　the　proposed　scheme　in　the　system　performance　and　feedback　load.　©2010　IEEE.
