Secrecy Analysis of Full-Duplex Power-Splitting SWIPT Networks with Artificial Noise
Abstract— This work conducts the secrecy analysis of full-duplex power-splitting simultaneous wireless
information and power transfer networks with artificial noise. The exact closed-form expressions of the COP,
SOP and RSP are derived, respectively, which are illustrated by numerical analysis. The results depict the
significance of the power-splitting ratio and the transmit signal-to-noise ratio (SNR). To be specific, the
secrecy performance is greatly improved with the increasing of the power-splitting ratio. In addition, it is
observed that the security of the system will get enhanced with the increasing of the power-splitting ratio at
first and then get reversed for a certain transmit SNR. Moreover, the value of the optimum transmit SNR
changes with different transmit SNR.
