Power-Time Splitting-Based Non-Linear Energy Harvesting in FD Short-Packet Communications

This paper investigates the reliability, goodput and energy efficiency (EE) performance of a energy harvesting (EH) based full-duplex (FD) cooperative internet-of-things (IoT) network for short-packet communications. We derive approximate closed-form expressions for the block error rate (BLER) and outage probability considering hybrid power-time splitting (PTS)-based practical non-linear EH model having the characteristics of sensitivity and threshold. Based on the derived results, we compare the performance of the considered FD non-linear EH based system with linear one. Moreover, we provide the system goodput and EE analysis using finite blocklength codes. Our analysis reveals key insights related to the impact of blocklength, packet size, self-interference and EH parameters on the reliability and EE performance of the considered IoT network.
