Directional modulation (DM), as a promising keyless physical-layer security technique, has rapidly developed within the last decade. This technique is able to directly secure wireless communications in the physical layer by virtue of the property of its direction-dependent signal modulation formatted transmission. This chapter reviews the development in DM technology over recent years, and provides some recommendations for future studies.
