Outage Probability Analysis for SWIPT Systems with Nonlinear Energy Harvesting Model

초록

This paper presents analytical results on outage probability performance for simultaneous wireless information and power transfer systems. In order to increase the capacity and coverage, we use a cooperative relay-aid network with spectrum sensing and energy harvesting (EH), which provides a better quality of service. A decode-and-forward relay is able to decode the received signals and to harvest energy from ambient sources at the same time by using a power splitting scheme. We also consider a nonlinear EH model that captures the nature characteristic of the EH receiver. Based on that setting, we derive the outage probability of the received signal-to-noise ratio and the achievable throughput of the primary communication system. Numerical simulations demonstrate the validity of the analytical results. © 2019 IEEE.
