Description
This paper investigates the throughput and outage probability (OP) of ratesplitting
multiple access (RSMA) in satellite–terrestrial communication networks.
By dividing user messages into common and private parts, RSMA
enhances spectral efficiency and user fairness while addressing hardware impairments
and co-channel interference. The proposed hybrid system model
is analyzed and compared with non-orthogonal multiple access (NOMA) under
various power allocation coefficients and channel conditions. Results show
that RSMA achieves lower OP and higher throughput than NOMA, particularly
in dense multi-cell deployments. Numerical evaluations further demonstrate
RSMA’s robustness against interference and hardware limitations, underscoring
its potential as a reliable solution for next-generation satellite–terrestrial relay
networks.
