    • Energy Efficient Relay Selection Algorithm for Virtual MIMO Cooperative Networks 

      El Cheikh, Mohamad; Simpson, Oluyomi; Sun, Yichuang (Institute of Electrical and Electronics Engineers (IEEE), 2020-07-27)
      In this paper, we propose a distance based energy efficient multiple relay selection algorithm for cooperative virtual Multiple-Input-Multiple-Output (MIMO). The fundamentals of this method is to forward the source signal ...

    • Power Optimisation and Relay Selection in Cooperative Wireless Communication Networks 

      El Cheikh, Mohamad (2018-06-14)
      Cooperative communications have emerged as a significant concept to improve reliability and throughput in wireless systems. In cooperative networks, the idea is to implement a scheme in wireless systems where the nodes can ...

    • Spectrum Sensing of DVB-T2 Signals in Multipath Channels for Cognitive Radio Networks 

      Simpson, Oluyomi; Sun, Yichuang; Abdulkadir, Yusuf; El Cheikh, Mohamad (VDE VERLAG GMBH, 2018-06-14)
      In this paper, spectrum sensing of digital video broadcasting-second generation terrestrial (DVB-T2) signals in different fading environments with energy detection (ED) is considered. ED is known to achieve an increased ...

    • Spectrum Sensing of DVB-T2 Signals using a Low Computational Noise Power Estimation 

      Simpson, Oluyomi; Abdulkadir, Yusuf; Sun, Yichuang; El Cheikh, Mohamad (2018-08-28)
      Cognitive radio is a promising technology that answers the spectrum scarcity problem arising from the proliferation of wireless networks and mobile services. In this paper, spectrum sensing of digital video broadcasting-second ...

    • STBC Based Pilot-Aided Channel Estimation Method for SFBC-OFDM Systems 

      Delestre, Fabien; Owojaiye, Gbenga; Sun, Yichuang; El Cheikh, Mohamad (Liverpool John Moores University, 2014-06-23)
      In this paper, an iterative channel estimation algorithm with joint detection is proposed for Multiple Input Multiple Output (MIMO) systems combined with Orthogonal Frequency Division Multiplexing (OFDM) also known as ...
