Robust beamforming design for RIS-UAV assisted two-layer RSMA systems with hardware impairments
This paper proposes a robust beamforming optimization algorithm for reconfigurable intelligent surface (RIS)-unmanned aerial vehicle (UAV) assisted two-layer rate-splitting multiple access (RSMA) system under imperfect successive interference cancellation (SIC). Firstly, fractional programming (FP) is employed to trans...
