    • Optimized collaborative spectrum sensing in energy harvesting cognitive radio networks 

      Adeli, Mohammad Hassan; Mohammadian, Fariba; Taherpour, Abbas; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time and energy resources in energy harvesting cognitive radio (CR) networks. The frame structures for sensing and ...

    • Optimized Error Probability for Weighted Collaborative Spectrum Sensing in Time-and Energy-Limited Cognitive Radio Networks 

      Taherpour, Abbas; Mokhtarzadeh, Hesameddin; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)
      In this paper, a collaborative energy-harvesting cognitive radio (CR) network is considered such that the transmitter of the secondary user (SU) is allowed to harvest signal energy of the primary user (PU) when the presence ...

    • Performance of non-coherent decode-and-forward relaying over time-varying fading channels 

      Safdari, Shahrzad; Taherpour, Abbas; Khattab,Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      Performance analysis of selection combining (SC) for decode-and-forward (DF) relaying in case of general time-varying Rayleigh fading channels is investigated. While auto-regressive (AR) time series model is applied in ...

    • Secure robust collaborative spectrum sensing in the presence of smart attackers 

      Pourgharehkhan, Zahra; Taherpour, Abbas; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In this paper, collaborative spectrum sensing to detect random signals corrupted by Gaussian noise in the presence of smart attackers is studied. Unlike to the most of related works, we consider a blind attacker detection ...

    • SFET-based multiple antenna spectrum sensing using the second order moments of eigenvalues 

      Sedighi, Saeid; Taherpour, Abbas; Gazor, Saeed; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      In this paper, we propose a new detector for multiantenna spectrum sensing in cognitive radios (CR) by exploiting the Separating Function Estimation Test (SFET) framework. Specifically, we consider a blind scenario for ...

    • The effect of additional statistical side information on multiple antenna spectrum sensing 

      Tabesh, Amirhossein; Taherpour, Abbas; Khattab, Tamer (2012 , Conference Paper)
      In this paper, we consider the problem of multiple antenna spectrum sensing in Cognitive Radios (CR) when some or all parameters are unknown. The Generalized Likelihood Ratio (GLR) test is the convectional method to solve ...

    • Theoretical accuracy analysis of indoor visible light communication positioning system based on time-of-arrival 

      Amini, Changeez; Taherpour, Abbas; Khattab, Tamer; Gazor, Saeed ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In this paper, an improved channel model and estimation for positioning in indoor environments using the visible light is presented. For positioning, the specific propagation and indoor channel model for visible light is ...

    • Time-frequency compressed spectrum sensing in cognitive radios 

      Monfared, Shaghayegh S.M.; Taherpour, Abbas; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2013 , Conference Paper)
      In this paper, we investigate the use of time-frequency analysis for improvement of spectrum sensing in cognitive radios and exploit compressed sensing (sampling) to reduce the extremely high sampling rate of signal in ...
