    • A framework for optimal cost media streaming in three-tier wireless networks 

      Al-Abbasi, Abubakr O.; Zahran, Ahmed H. ( Springer New York LLC , 2017 , Article)
      Heterogeneous networking is envisioned as a key solution for accommodating the traffic surge resulting from resource demanding applications such as video streaming. In this paper, the diversity in cost, coverage, and ...

    • A general framework for the design and analysis of sparse FIR linear equalizers 

      Al-Abbasi, Abubakr O.; Hamila, Ridha; Bajwa, Waheed U.; Al-Dhahir, Naofal ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      Complexity of linear finite-impulse-response (FIR) equalizers is proportional to the square of the number of nonzero taps in the filter. This makes equalization of channels with long impulse responses using either zero-forcing ...

    • Design and analysis framework for sparse FIR channel shortening 

      Al-Abbasi, Abubakr O.; Hamila, Ridha; Bajwa, Waheed U.; Al-Dhahir, Naofal ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      A major performance and complexity limitation in broadband communications is the long channel delay spread which results in a highly-frequency-selective channel frequency response. Channel shortening equalizers (CSEs) are ...

    • Design and Analysis of Sparsifying Dictionaries for FIR MIMO Equalizers 

      Al-Abbasi, Abubakr O.; Hamila, Ridha; Bajwa, Waheed U.; Al-Dhahir, Naofal ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)
      In this paper, we propose a general framework that transforms the problems of designing sparse finite-impulse-response linear equalizers and nonlinear decision-feedback equalizers, for multiple antenna systems, into the ...

    • Secure AF Relaying in Power-Constrained UAV Networks 

      Samara, Lutfi; AlAbbasi, Abubakr O.; El Shafie, Ahmed; Hamila, Ridha; Al-Dhahir, Naofal ( IEEE , 2021 , Conference Paper)
      This paper proposes a secure amplify-and-forward (AF) relaying scheme in unmanned aerial vehicle (UAV) networks while accounting for the power consumption limitations of UAVs. Since a UAV's battery life is limited, we ...

    • Sparsifying dictionary analysis for FIR MIMO channel-shortening equalizers 

      Al-Abbasi, Abubakr O.; Hamila, Ridha; Bajwa, Waheed U.; Al-Dhahir, Naofal ( IEEE , 2016 , Conference Paper)
      In this paper, we propose a general framework that transforms the problems of designing sparse finite-impulse response channel-shortening equalizers and target impulse response filters for multiple antenna systems into the ...
