Alternative direction for 3D orthogonal frequency division multiplexing massive MIMO FDD channel estimation and feedback

In this study, downlink channel estimation of three-dimensional massive multiple-input multiple-output (3D-MIMO) system operating in the frequency division duplexing (FDD) mode is considered. Inspired by the channel sparsity property, this study proposes a compressive sensing algorithm to exploit th...
