Hence, Spatial Modulation ( SM ) on downlink can be facilitated by using angular indices of antennas in 2-dimensions and the spherical coordinates of antennas in three dimensions. It is concluded that the performance measures such as spectral efficiency improve with this innovative SM schemes. Further, the implementation of these ideas in real world communication systems is really feasible Keyphrases: Downlink, Spatial Modulation, polar coordinates, spectral efficiency, spherical coordinates
