Abstract
In this paper, we consider the problem of nonregenerative two-way secure relay beam forming (SRB) for cognitive radio network (CRN) under the background of the simultaneous wireless information and power transfer (SWIPT). Our objective is to maximize sum rate under the transmit power constraint at the relay, energy harvesting (EH) constraint at the EH device and the interference constraint from secondary user (SU). The formulated problem is a nonconvex problem. We firstly propose a two-dimensional (2D) search scheme which provides an upper bound to the formulated problem; for decreasing the computation complexity, we propose a sequential parametric convex approximation (SPCA) based iteration scheme and obtain a local optimal solution. Simulation results have shown that SPCA based iteration scheme performs almost close to 2D search schemes, and has lower computation complexity.
