摘要

The work studies emerging technologies that help boost data rate and energy efficiency of wireless communication systems. Firstly, rate-splitting (RS) multiple access (MA) is a prominent MA paradigm for high data rate transmission. Secondly, simultaneous transmitting and reflecting intelligent reflecting surface (STAR-IRS) is one of solutions to deteriorate effects of obstacles and attenuation over fading channels, significantly ameliorating communication reliability. In spite of their potential advantages, limited power of devices in these networks requires an efficient power solution. Thereby, full-duplex (FD) combined with energy harvesting (EH) might be the best solution for limited power. To assess their throughput under such possibilities, the work proposes explicit formulas for crucial indicators over Nakagami-m fading channels, and Monte-Carlo simulation (MCS) is exploited to confirm our exact analysis. The results show that these combinations (RSMA with FD EH and STAR-IRS) significantly enhance system efficacy. By strictly designating system settings, we can strengthen achievements and eliminate outages completely. Furthermore, the study provides evidence that the proposed system is more effective than two comparative systems: orthogonal MA (OMA) and nonorthogonal MA (NOMA) with FD EH and STAR-IRS.
