    • Bandpass sampling of multiband signals by using geometric approach 

      Saatçı, Esra; Saatçı, Ertuğrul; Akan, Aydın (IEEE, 345 E 47th St, New York, Ny 10017 USA, 2017)
      This paper presents a simple and fast approach to f nd a minimum sampling frequency for multi-band signals. Instead of neighbor and boundary conditions, constraints on the sampling frequency were derived by using the ...
    • Channel estimation for spatial modulation orthogonal frequency division multiplexing systems 

      Acar, Yusuf; Doğan, Hakan; Panayırcı, Erdal (IEEE, 345 E 47th St, New York, Ny 10017 USA, 2015-10-14)
      A combination of spatial modulation and orthogonal frequency division multiplexing (SM-OFDM) has been recently proposed for multicarrier systems while assuming the perfect channel state information (P-CSI) available at the ...
    • Fundamental frequency estimation for heterophonical Turkish music by using VMD 

      Unknown author (IEEE, 345 E 47th St, New York, Ny 10017 USA, 2016)
      In this study, a new method is presented for the fundamental frequency estimation of heterophonical Turkish makam music recordings that include percusssive instrument by using Variational Mode Decomposition (VMD). VMD is ...
    • Multiple frequency estimation by using improved variational mode decomposition 

      Öztürk Şimşek, Berrak; Akan, Aydın (IEEE, 345 E 47th St, New York, Ny 10017 USA, 2017)
      In this study, an improved Variational Mode Decomposition method is introduced and applied to the multi frequency estimation problem in heterophonical Turkish maqam music recordings. The main purpose of this method is to ...
    • Pilot symbol assisted channel estimation for 4x4 space time block coded spatial modulation systems 

      Acar, Yusuf; Doğan, Hakan; Panayırcı, Erdal (IEEE, 345 E 47th St, New York, Ny 10017 USA, 2015)
      Recently, spatial modulation (SM) and space-time block coding (STBC) are combined to take advantage of the benefits of both while avoiding their drawbacks for multiple-input and multiple-output (MIMO) systems. The pioneering ...
    • Wiener-Hopf Analysis of Grooved Coaxial Waveguide 

      Büyükaksoy, İbrahim Alinur; Hacıvelioğlu, Ferda; Uzgören, G. (IEEE, 345 E 47th St, New York, Ny 10017 USA, 2008)
      A Wiener-Hopf analysis is provided for the propagation of the dominant TEM mode in a coaxial waveguide with a dielectric filled groove on the outer conductor. Some graphical results showing the effects of the groove depth ...
