Abstract
Based on capacity maximisation metric, an iterative swapping antenna selection method is proposed for massive multiple-input multiple-output (MIMO). Then a ‘local’ swapping algorithm is proposed for massive MIMO antenna selection, which swaps the target antennas ‘locally’. A ‘global’ swapping algorithm is also proposed to reduce the computational complexity, which exchanges the target antennas ‘globally’. Both of the proposed algorithms are near optimal, due to the consideration of the influences of the unselected antennas and the selected ones on the antenna to be selected. Last, numerical simulations are provided to validate the proposed algorithms.
