    • Adaptive network coding for spectrum sharing systems 

      Chun Y.J.; Hasna , Mazen; Ghrayeb A. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      In this paper, we propose an adaptive network coding scheme for cognitive relay networks comprising multiple secondary sources communicating with a common destination in the presence of multiple primary users. Conventional ...

    • Performance enhancement of cognitive relay networks using regression functions 

      Tourki, Kamel; Hasna, Mazen O. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In a spectrum sharing relay-aided secondary network, the design objective shifts from minimizing the violation of the primary system constraints when using the outdated channel state information (CSI), to making the best ...
