Synthesis of Sparse Linear Array for Directional Modulation via Convex Optimization

The design of a directional modulation (DM) signal by a phased array is one of the important topics in the field of physical layer security communication. In this paper, we synthesize a sparse array for DM based on convex optimization. The main idea is that a nonconvex optimization problem associated with ℓ0-norm is formulated for synthesizing a sparse array. To solve this nonconvex optimization p...
