Abstract:

Joint transceiver design for achieving energy efficiency maximization was studied in multi-user downlink systems with simultaneous wireless information and power transfer. An improved Dinkelbach method was proposed. Specifically, the problem is converted to a series of subtraction form problems following the basic idea of Dinkelbach method. By introducing a set of auxiliary variables, the subtraction form problem is further equivalently cast as a weighted mean-square-error minimization problem, which is solved by using concave-convex procedure and second-order-cone programming(SOCP). Simulation results validates the efficiency of the proposed method.

Key words: radio frequency, simultaneous wireless information and power transfer, improved Dinkelbach method, energy efficiency optimization
