Security of full-duplex jamming SWIPT system with multiple non-colluding eavesdroppers

Abstract

In this paper, the secrecy performance of full-duplex jamming SWIPT system is conducted where multiple eavesdroppers intercept the confidential information individually. The closed-form expressions of the connection outage probability (COP), the secrecy outage probability (SOP), the reliable-secure probability (RSP) and the secrecy throughput are obtained, which depict the secrecy performance of the system intuitively. The results demonstrate the significance of the power-splitting ratio, the transmit signal-to-noise ratio (SNR) and the secrecy information rate on the system security. All the observations indicate the existence of a optimum pair of the secrecy information rate and the power splitting ratio which maximize the secrecy throughput. Numerical results are provided for the validation of the analysis.
