摘要:
In this talk, a special robust optimization problem is considered, which arises from the physical layer security problem in wireless communications. We jointly design the relay beamforming weights with imperfect channel state information, to minimize the relay total transmit power, while ensuring users’ Quality of Service (QoS) and preventing the information being eavesdropped. An algorithm based on line search is proposed. In each iteration we determine the line search direction and the step size by solving two Quadratically Constrained Quadratic Programming (QCQP) subproblems and a one-dimensional subproblem respectively. Simulation results indicate that the proposed algorithm has better performances compared to the state of the art.
