Abstract

The first contribution of this letter is to correct an error in the formulation of the Low-Complexity Euclidean Distance optimized Antenna Selection scheme for Spatial Modulation (SM), (SM-EDAS-LC). Secondly, due to a simulation error the Monte Carlo simulation results presented in the above letter for SM-EDAS-LC are erroneous, thus we present the correct results for the scheme, which demonstrates that the error performance in fact outperforms that of Capacity Optimized Antenna Selection for SM. The third contribution is to propose two modifications to SM-EDAS-LC that significantly reduce the computational complexity.
