NOMA-based Improper Signaling for Multicell MISO RIS-assisted Broadcast Channels
Mohammad Soleymani, Ignacio Santamaria, Eduard Jorswieck +1
In this paper, we study the performance of reconfigurable intelligent surfaces (RISs) in a multicell broadcast channel (BC) that employs improper Gaussian signaling (IGS) jointly w…
Legitimate against Illegitimate IRSs on MISO Wiretap Channels
Sepehr Rezvani, Pin-Hsun Lin, Martin Le +1
The low-cost legitimate intelligent reflecting surfaces (IRSs) are applied to the wiretap channel in physical layer security to enhance the secrecy rate. In practice, the eavesdrop…
