    • Effective capacity of cognitive radio links: Accessing primary feedback erroneously 

      Butt M.M.; Anwar A.H.; Mohamed A.; El Batt T. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)
      We study the performance of a cognitive system modeled by one secondary and one primary link and operating under statistical quality of service (QoS) delay constraints. We analyze the effective capacity (EC) to quantify ...

    • Interference-based optimal power-efficient access scheme for cognitive radio networks 

      Anwar A.H.; El Shafie A.; Mohamed A.; Elbatt T.; Guizani M. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      In this paper, we propose a new optimization-based access strategy of multi-packet reception (MPR) channel for multiple secondary users (SUs) accessing the primary user (PU) spectrum. We devise an analytical model that ...
