A low-complexity power allocation algorithm for multiple-input–multiple-output spatial modulation systems
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 multipleinput 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 to the exhaustive-search based algorithm. Our simulation results show that the proposed algorithm provides beneficial bit error ratio (BER) performance improvements compared to both the conventional SM and the PA based spatial multiplexing arrangements.

Abstract
In this paper, a low-complexity Euclidean distance-based power allocation (PA) algorithm is proposed for spatial modulation (SM) aided multipleinput 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 to the exhaustive-search based algorithm. Our simulation results show that the proposed algorithm provides beneficial bit error ratio (BER) performance improvements compared to both the conventional SM and the PA based spatial multiplexing arrangements.
