Spatial modulation techniques for 5G wireless networks

Abstract

5G wireless communications networks, which are aimed to be introduced around 2020, are expected to provide 10 times higher spectral and energy efficiency than 4G wireless communications networks that are currently used in several countries. Different layers of next generation communications systems should be redesigned to reach these challenging goals. In this study, we deal with the potential and some implementation scenarios of spatial modulation (SM) techniques for the physical layer of 5G wireless networks. The recent advances in SM technologies are reviewed and future research directions on the use of SM techniques towards high spectral and energy efficient 5G wireless communications networks are discussed.
