    • An FPGA implementation architecture for decoding of polar codes 

      Pamuk, Alptekin (IEEE, 2011)
      Polar codes are a class of codes versatile enough to achieve the Shannon bound in a large array of source and channel coding problems. For that reason it is important to have efficient implementation architectures for polar ...
    • Lumped element modeling of CMUT arrays in collapsed mode 

      Aydoğdu, Elif; Özgürlük, A.; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 2014-09)
      This study focuses on modeling collapsed modeoperation of CMUT arrays, and obtaining a small signal lumped element model for collapsed mode operation. Having the large signal model for single CMUT from previous studies, ...
    • Resonances and nonuniformities in CMUT elements or arrays 

      Atalar, Abdullah; Köymen, Hayrettin (IEEE, 2014-09)
      We determine the response of individual cells of a CMUT array immersed in water using the small-signal equivalent circuit of a single cell and radiation impedances. Using a numerically efficient technique, we are able to ...
