• On the Performance of RIS-Assisted Dual-Hop UAV Communication Systems 

      Yang L.; Meng F.; Zhang J.; Hasna , Mazen; Renzo M.D. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      In this paper, to further improve the coverage and performance of unmanned aerial vehicle (UAV) communication systems, we propose a reconfigurable intelligent surface (RIS)-assisted UAV scheme where an RIS installed on a ...
    • Secrecy Performance Analysis of RIS-Aided Wireless Communication Systems 

      Yang L.; Yang J.; Xie W.; Hasna , Mazen; Tsiftsis T.; ... more authors ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      In this work, we study the secrecy performance of a reconfigurable intelligent surfaces (RIS)-aided wireless communication system in the presence of an eavesdropping user. Specifically, we assume that the RIS is placed ...
