摘要
The beamforming technique is increasingly used in multi-user relay networks for directional signal transmission. The main purpose of this paper is to design beamforming coefficients to minimize the total relay transmitted power under destination Quality-of-Service (QoS) constraints. There are some techniques have been proposed previously to solve the class of these problems such as: semidefinite relaxation approach (SDR) and convex second-order cone programing form (SOCP). We propose another method named Difference of Convex functions Algorithm (DCA) and evaluate the performance of this approach.
