In order to reduce the feedback load of multi-user orthogonal frequency division multiplexing（ OFDM）-based wireless systems,a practical limited bits feedback precoding algorithm is proposed with direct source-destination link based on amplify-andforward cooperative relay network under frequency selective fading channels.Using joint minimum mean square error（ MMSE） filter,the receiving decoding matrix is designed for each user in the paper.Source precoding（ beamforming） matrix is optimized with c...
