In this paper, we give a unified performance optimization for secrecy wireless information and power transfer over interference channels, where an external eavesdropper is also interested in the confidential message. We propose to perform cooperative energy beamforming between two sources to confuse the eavesdropper while satisfying the requirements on the minimum amounts of individual harvested energy,...
In this letter, we study the problem of secrecy wireless information and power transfer in a cognitive relay network (CRN), where a secondary transmitter (ST) aids the signal transmission from a primary transmitter to a primary receiver (PR), while it also transmits its own signal to a second receiver (SR). Both the PR and SR decode information and harvest energy from the received signals based on...
