Abstract

In this paper, we consider the security communications in an OFDM - based SWIPT system by adding a full-duplex, friendly jammer with wireless powered equipment between a transmitter (Tx) and an information receiver (IR) and an energy receiver (ER) which called (regarded as) a potential eavesdropper. We propose a scheme that under friendly jammer protection TX sends source messages to IR and jammer, the jammer sends jammer signal to ER and IR while receiving information from Tx to confound potential eavesdroppers but can be eliminated at IR. Our goal is to maximize the sum secrecy information rate by jointly optimizing the power allocation at the Tx and jammers while satisfying the energy harvesting at the ER.
