Solar Collectors, Non-concentratingethods. In this paper, a radial basis function (RBF) based neural network is proposed for fast directional modulation design, which is trained by data corresponding to sets of transmission direction and interference direction angles with the corresponding weight coefficients. The proposed method tak

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 ti
