    • Outage performance of incremental relaying networks with OFDM subcarriers mapping schemes 

      Gouissem A.; Hasna , Mazen; Hamila R. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)
      The scarcity of radio resources coupled with the high data rate demands in the last few years, induced incremental relaying techniques one of the most promising technologies. This is simply because it allows reaping spatial ...

    • Performance of Mixed RF/FSO with Variable Gain over Generalized Atmospheric Turbulence Channels 

      Yang L.; Hasna , Mazen; Gao X. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      In this paper, we consider a free-space optical (FSO) communication scheme with the help of a variable gain relay where the links from the source to the relay are radio-frequency (RF) links while the links between the relay ...

    • Securing cognitive radio networks against primary user emulation attacks 

      Yu, Rong; Zhang, Yan; Liu, Yi; Gjessing, Stein; Guizani, Mohsen ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      CR is a promising technology for next-generation wireless networks in order to efficiently utilize the limited spectrum resources and satisfy the rapidly increasing demand for wireless applications and services. Security ...
