Abstract
En 中文
The study investigates the security susceptibilities of rate-splitting multiple access (RSMA) systems powered by harvested energy, focusing on threats from both external and internal eavesdropping. External eavesdropping arises from unauthorized wiretappers unrelated to RSMA, whereas internal eavesdropping is an inherent issue of successive interference cancellation, wherein any RSMA receiver may intercept others' signals. This study also evaluates the security capability of energy harvesting-assisted RSMA considering realistic energy harvesting conditions. The proposed evaluation framework is confirmed through Monte Carlo simulation. The findings reveal that, across various operational scenarios, RSMA provides superior security compared to orthogonal multiple access and non-orthogonal multiple access in energy harvesting wireless systems.
