      Distributed Space Time Block Coding for Asynchronous Cooperative Communication Systems

      El Astal, Mohammed Taha Omer (the islamic university, 2011)
      Multiple-Input-Multiple-Output (MIMO) communication techniques have been an important area of focus for 4th generation wireless systems. This is mainly because of their potentials for high capacity, increased diversity, ...
    • Office Appliances Identification and Monitoring using Deep Leaning based Energy Disaggregation for Smart Buildings

      El Astal, Mohammed; Abu-Hudrouss, Ammar M.; Frey, Georg; Kalloub, Mohammed (IEEE, 2020-10)
      Analysis of electrical energy metering profiles has experienced a substantial increase of research activity in recent years. This smart metering is a tool for monitoring energy usage and users’ behaviors as a pre-requisite ...
    • On Using Quadrature Spatial Modulation in Multi-User Networks

      El Astal, Mohammed; Al Habbash, Alaa; Abu-Hudrouss, Ammar M. (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)
      Quadrature spatial modulation (QSM) has been recently proposed for MIMO communication systems. It comes to enhance the overall throughput over conventional spatial modulation (SM) techniques. This article investigates the ...

      Signed Quadrature Spatial Modulation for MIMO Systems

      Abu-Hudrouss, Ammar M.; El Astal, M.-T.; Al Habbash, Alaa; Aissa, Sonia (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Quadrature spatial modulation (QSM) was recently proposed to increase the spectral efficiency of spatial modulation. In QSM, the real and imaginary parts of a symbol are transmitted independently from different antennas. ...
    • Space-time transmission scheme for asynchronous cooperative communications networks

      El Astal, Mohammed; Al Habbash, Alaa; Abu-Hudrouss, Ammar M. (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)
      In this paper, an effective transmission scheme is proposed for asynchronous cooperative networks with two relays. The need for synchronization is obviated by allowing a single relay to be active in each time-slot of the ...

      Super-orthogonal double space-time trellis code

      Tubail, Mohammed A.; Abu-Hudrouss, Ammar M.; El Astal, Mohammed (Elsevier BV, 2020)
      This study develops a new class of super-orthogonal trellis codes for four transmit antennas based on double space-time codes. The transmit antennas are divided into two groups, each having two transmit antennas. The ...
