    • A General Framework for Designing Sparse FIR MIMO Equalizers Based on Sparse Approximation 

      Al-Abbasi, Abubakr Omar; Hamila, Ridha; Bajwa, Waheed; Al-Dhahir, Naofal ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)
      In broadband communications, the long channel delay spread, defined as the duration in time, or samples, over which the channel impulse response (CIR) has significant energy, is too long and results in a highly-frequency-selective ...

    • 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 ...
