A Low-Complexity Power Allocation Algorithm for Multiple-Input–Multiple-Output Spatial Modulation Systems

In this paper, a low-complexity Euclidean distance-based power allocation (PA) algorithm is proposed for spatial modulation (SM)-aided multiple-input–multiple-output (MIMO) systems. The proposed algorithm only exploits the Euclidean distances of a few dominant error vectors for optimizing the PA matrix; hence, its computational complexity is considerably reduced compared with the exhaustive-search-based algorithm. The simulation results show that the proposed algorithm provides beneficial bit error ratio (BER) performance improvements compared with both the conventional SM- and PA-based spatial multiplexing arrangements.
