Abstract:
This paper considers a fast fading wireless powered wiretap channel, where an energy constrained information source, powered by a dedicated power beacon, sends a secret message to a legitimate user using the artificial noise (AN) scheme in the presence of a passive eavesdropper. Based on a two-phase time division protocol, the ergodic secrecy throughput is derived. Furthermore, the optimal time-switching factor and power-allocation factor are studied for maximizing the ergodic secrecy throughput. Numerical results are presented to validate our theoretical results.
