چکیده :
In this work, we propose a beamforming design for secure wireless communication via Simultaneous transmission and reflection reconfigurable intelligent surface (Star RIS). We consider a practical scenario with imperfect channel state information of an eavesdropper. We maximize the sum rate (SR) of legitimate users by jointly optimizing active and passive beamforming under the maximum tolerable rate leakage of the eavesdropper and power consumption constraint of the AP. The optimization problem is non-convex and solved with the assistance of the path-following technique, S-procedure and general sign definiteness to approximate the non-convex part and semi infinite inequalities and finally, the penalty concave-convex procedure (PCCP) is implemented. Simulation results show the superiority of Star-RIS over conventional RIS and higher performance with lower channel estimation error.
