Title
Secure beamforming and artificial noise design for simultaneous wireless information and power transfer in interference networks.
Abstract
We study a secure communication of a two-user interference network. In this network, two transmitters send information and artificial noise simultaneously to two users and energy receivers (ERs), and ERs are likely to perform as eavesdroppers. We propose a joint beamforming and artificial noise design to maximize the total energy harvested by ERs subject to the secrecy sum rate requirement and power constraints. The proposed design constitutes an optimization problem, which is non-convex yet can be further transformed into a two-stage problem. In the first stage, by introducing an auxiliary variable, we can reformulate the non-convex as a second-order cone program (SOCP) problem, and the constrained concave convex procedure based algorithm is proposed to make this SOCP problem tractable. In the second stage, the auxiliary variable is obtained by the one-dimensional line search. Numerical results demonstrate the effectiveness of the proposed algorithm.
