Secrecy Enhancing Scheme for Spatial Modulation Using Antenna Selection and Artificial Noise
In this paper, we present a new secrecy-enhancing scheme for the spatial modulation (SM) system, by considering imperfect channel state information (CSI).In the proposed scheme, two antennas are activated at the same time.One of the activated antennas transmits information symbols along with artificial noise (AN) optimized under the imperfect CSI c
