For 3D MEMO precoding systems over spatially correlated channel, a novel limited feedback method is proposed by utilizing the nature of the spatial correlation and clustering of the subchannel of transmitting and receiving antenna pair. In this method, due to the co-phased and spatial-correlated characteristics of the vertical channel for 2D antenna array, each vertical antenna is assumed to have the same horizontal phase and all the horizontal channels only feedback one precoding matrix index… CONTINUE READING
