Comments and Corrections Correction to “Transmit Antenna Selection for Precoding-Aided Spatial Modulation”

Abstract

In the above article [1], the authors found some mistakes in real summation (RS) computations. As the computational complexity in terms of real summation (RS) is re-evaluated in the revision process, we didn’t consider 2 RSs additionally required for a complex multiplication. The resulting RS complexity expressions of (25) and (28), and RS complexity in Table 3 were mistaken. They have no impact on the discussion and conclusions in the paper. The corrected results are given here.
