Outage analysis of superposition modulation aided network coded cooperation in the presence of network coding noise [PDF]
, 2015 We consider a network, where multiple sourcedestination pairs communicate with the aid of a half-duplex relay node (RN), which adopts decode-forward (DF) relaying and superposition-modulation (SPM) for combining the signals transmitted by the source ...

Secrecy Outage Probability Fairness for Intelligent Reflecting Surface-Assisted Uplink Channel [PDF]
, 2022 This paper investigates physical layer security (PLS) in the intelligent reflecting surface (IRS)-assisted multiple-user uplink channel. Since the instantaneous eavesdropper's channel state information (CSI) is unavailable, the secrecy rate can not be ...
