摘要

Rate-splitting multiple access (RSMA) in energy harvesting (EH) full-duplex (FD) underlay networks (RSMAehFDun) allows an EH- and FD-enabled secondary transmitter to simultaneously deliver RSMA signals to multiple receivers within the frequency band licensed to primary transmitters (PTs), using the energy harvested from the interference generated by these PTs. This approach enhances spectral efficiency, spectral utilization, and energy efficiency. The study investigates the throughput performance of RSMAehFDun under arbitrary fading conditions, with theoretical findings verified by Monte Carlo simulation. The findings illustrate that RSMA consistently achieves higher reliability than traditional multiple access schemes in EH FD underlay networks.
