    • Adaptive hierarchical cooperative communication using energy harvesting relay 

      Khakzad, Hamidreza; Shakeri, Reza; Taherpour, Abbas; Khattab, Tamer (2013 , Conference Paper)
      In this paper, we present an adaptive wireless communication system with energy harvesting relay where, two sources wish to send data to a destination via an energy harvesting relay that utilizes hierarchical constellation. ...

    • Capacious spread spectrum watermarking utilizing hadamard matrix 

      Tafreshi, Hossein Fami; Shakeri, Reza; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In this paper, a new watermarking method based on spread spectrum technique, which we call capacious spread spectrum (CSS) is proposed. In this method, unlike the traditional spread spectrum watermarking (TSS), more than ...

    • Dynamic interference-limited relay sharing in cognitive radio networks by using hierarchical modulation 

      Khakzad, Hamidreza; Taherpour, Abbas; Shakeri, Reza; Khattab, Tamer ( Institution of Engineering and Technology , 2017 , Article)
      Sharing a relay in cognitive radio (CR) networks in order to enhance the secondary user's (SU's) performance in an interference-limited scheme is investigated. It is assumed, by utilising hierarchical modulation, a shared ...

    • Error probability analysis of energy harvesting relay-Aided cooperative network using hierarchical modulation 

      Shakeri, Reza; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In this paper, we investigate the performance of energy harvesting relay-Aided cooperative system wherein, the source node transmits hierarchical signal to the relay and destination nodes. But, since in cooperative networks ...

    • Impact of stochastic RF energy harvesting relay on wireless point-to-point network 

      Shakeri, Reza; Khakzad, Hamidreza; Taherpour, Abbas; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In this paper, we study a general practical stochastic energy harvesting (EH) model where in, an EH relay is able to harvest energy from the radio frequency (RF) radiation in a super capacitor. The different aspects of ...

    • Multiuser scheduling on downlink communications by using adaptive hierarchical modulation 

      Khakzad, Hamidreza; Shakeri, Reza; Taherpour, Abbas; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      In this paper, we propose a novel downlink system that is able to maximize the number of users which could be served with high correct decoding probability while, minimizing the total consumed energy for data reconstruction ...

    • Optimal power allocation and relay selection in two-way multi-relay cooperative communication 

      Shakeri, Reza; Taherpour, Abbas; Khakzad, Hamidreza; Khattab, Tamer (2013 , Conference Paper)
      In this paper, we investigate the power allocation in two-way multi-relay assisted cooperative network in which the relays operate in decode-and-forward (DF) protocol. In the proposed method for choosing the best relay ...
