Secrecy Rate and Harvested Energy Trade-Off for MISO Channels with Finite-Alphabet Inputs by Aghdam, Sina Rezaei, Duman, Tolga M.

“… (potential eavesdropper), and we propose a precoder optimization approach. Then, we investigate the case where only perfect CSI of the information receiver is available along with the statistical CSI of the energy receiver. Our numerical results demonstrate the efficacy of the proposed solutions…”
