Securing Intelligent Reflecting Surface (IRS)–Aided NOMA Networks in Covert Wireless Communication Using Jammer

International Journal of Communication Systems
ABSTRACTIn this paper, an intelligent reflecting surface (IRS)–assisted non‐orthogonal multiple access (NOMA) network is proposed in a multi‐user scenario where the transmitter communicates with its receiver covertly by helping a friendly jammer. In this network, an adversary detects the communication existence of the users in the frequency band while ...
