PERFORMANCE ANALYSIS OF ENERGY HARVESTING AND RECONFIGURABLE INTELLIGENT SURFACE AIDED COOPERATIVE COMMUNICATION OVER RAYLEIGH FADING CHANNEL

Abstract

In this research, we're employing Reconfigurable Intelligent Surfaces (RIS) and energy harvesting to figure out the cooperative communications throughput and outage probability in Rayleigh fading channel. The source harvests energy through the utilization of the Radio Frequency (RF) signal that the source receives from the Power Beacon (PB). Any node that emits a radio signal can serve as Node PB. The collected energy is used to transmit data to an intended recipient with the aided RIS. This work gives the closed expression of outage probability of the RIS-aided system with or without direct transmission link based on numerous system quality of service (QoS) requirements and investigates the impact of energy harvesting (EH) duration on the outage performance as well as exploits the Goden Section search method to optimize time splitting (TS) factor.
