… The imperfect CSI is also modeled in [11] without considering NOMA systems. In summary,
STAR-RIS enabled downlink secure NOMA networks under imperfect CSI remains an open …

… Based on the estimated CSI, we derive the ergodic sumrate of the STAR-RIS aided NOMA
systems with perfect SIC decoding algorithms considering both the channel estimation error …

… Thus, we propose a DF-RIS assisted NOMA network under imperfect CSI and explore a …
a STAR-RIS assisted NOMA network to provide full-space transmission security. The STAR-RIS …

… For the optimization problem in the perfect CSI scenario, we develop a penalty-… imperfect
CSI scenario, this paper is the first work to study the robust beamforming design for STAR-RIS-…

… and imperfect CSI should also be considered for STAR-RIS-aided systems. Due to the fact
that the BS and RIS are often installed at higher locations with few barriers and RIS generally …

… In order to fully unleash the potential and advantages of STAR-RIS and active RIS, the …
In addition, we investigate the case of channel conditions for perfect CSI and imperfect CSI, …

… Under this general setup, we derive the downlink achievable spectral efficiency (SE) of a
STAR-RIS-assisted mMIMO system with imperfect CSI and correlated fading in closed form that …

… Besides, the authors in [7] focused on the uplink transmission of RIS-aided MISO systems
with imperfect CSI, and the superiority of the system over the traditional MISO system was …

… , we undertake the robust design for the secure STAR-RIS-SWIPT system to guarantee the
… progress on RIS/STAR-RIS-assisted wireless communication systems under imperfect CSI, …

… With strict proof, we show that, to achieve the optimal solution, the STAR-RIS should work
in … and the STAR-RIS works in T mode. The optimal energy splitting ratio of the STAR-RIS or …
