Given its ability to intelligently modify the wireless propagation environment, reconfigurable intelligent surface (RIS) emerges as a promising technology to enhance the capacity of multicast systems. This paper analyzes the ergodic rate (ER) of a RIS-assisted multicast system with finite-alphabet i...
