Abstract

As a physical layer security technique, directional modulation (DM) is normally realized using a fully digital structure due to its easy and flexible hardware design. However, for a large antenna array, such as the case of massive MIMO, to reduce the cost and power consumption, a hybrid digital and analog beamforming structure is widely adopted. In this paper, the DM design problem is studied based on such a hybrid implementation for the first time. As a representative example, the interleaved subarrays are used for the proposed design. Design examples are provided to show the effectiveness of the proposed design.
