The joint beam-forming and antenna selection problem encountered in modern multi-user massive multiple input multiple output (MIMO) communication systems is solved using the projected fast iterative shrinkage–thresholding algorithm (ISTA). The algorithm aim is to find the suboptimal set of transmitt...
