To further improve the secrecy rate, a joint optimization scheme for the reconfigurable
intelligent surface (RIS) phase shift and the power allocation is proposed in the untrusted …

In this paper, a distributed multiple-intelligent reflecting surface (IRS)-assisted multiple-input
single-output (MISO) system is studied. Since IRS is operated in a passive manner, only …

Reconfigurable intelligent surface (RIS) is a promising technology to reconfigure the
wireless channel, which can be used for signal modulation with low hardware cost. In this …

We focus on the secure performance metrics at the legitimate users, ie secure outage
probability (SOP) and secrecy capacity, to quantify the secrecy performance of NOMA-RIS …

Energy efficiency and security are strongly required performance metrics for future wireless
communication systems. As a high energy-efficiency technology, intelligent reflecting …
