    • Base station cooperation in orthogonal frequency division multiple access (OFDMA) systems 

      Tokel, T.B.; Aktaş, D. (2009)
      Achieving the targeted data rates for next generation wireless communication systems requires using frequency reuse ratio 1 in these systems, but this in turn results in significant intercell interference observed especially ...
    • Connectivity analysis of an AUV network with OFDM based communications 

      Bereketli, A.; Tümçakir, M.; Yazgi, I.; Yeni, B.; Koseoglu, M.; Duman, T. M. (Institute of Electrical and Electronics Engineers Inc., 2017)
      Autonomous underwater vehicle (AUV) networks play a crucial role in tactical, commercial, and scientific applications, where reliable and robust communication protocols are needed due to the challenging characteristics of ...
    • Cooperative transmission for multiuser MIMO systems 

      Yazarel, Y.K.; Aktaş, D. (2008)
      In this work, we investigate the problem of jointly determining the optimal transmission scheme at the base stations in a cooperative multiuser multiple antenna system. In this optimization problem, different than majority ...
    • One and two dimensional LiNbO3 photonic crystals 

      Simsek, S.; Mamedov, A.M.; Ozbay, E. (IEEE Computer Society, 2013)
      In this report, we present an investigation of the optical properties and band structure calculations for the photonic crystal structures (PCs) based on one-dimensional (1D) and two-dimensional (2D) ferroelectric LiNbO3 ...
