Abstract
In this study, an reconfigurable intelligent surface (RIS)-enabled linear interference alignment (IA) is examined for multi-user multiple-input multiple-output (MU-MIMO) in a presence of an eavesdropper. Modified precoder and postcoder matrix designs are introduced to minimize interference for legitimate users which is used as ensuring secure communications. According to our findings, the secrecy sum rate of the IA-based RIS-enabled MU-MIMO outperforms that without IA case due to the intensive interference of the communication environment.
