• On spectrum sharing between energy harvesting cognitive radio users and primary users 

      El Shafie A.; Ashour M.; Khattab T.; Mohamed A. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
