Energy Harvesting for Physical-Layer Security in OFDMA Networks

  title={Energy Harvesting for Physical-Layer Security in OFDMA Networks},
  author={Meng Zhang and Yuan Liu},
  journal={IEEE Transactions on Information Forensics and Security},
In this paper, we study the simultaneous wireless information and power transfer in downlink multiuser orthogonal frequency-division multiple access systems, where each user applies power splitting to coordinate the energy harvesting and secrecy information decoding processes. Assuming equal power allocation across subcarriers, we formulate an optimization problem to maximize the aggregate harvested power of all users while satisfying secrecy rate requirements of individual users by joint… CONTINUE READING
