  • A New Companding Technique for Papr Reduction in Ofdm Communication Systems 
    Gazi, Orhan (2011)
    One of the major disadvantages of OFDM communication systems is their high peak-to-average power ratio (PAPR) which degrades system performance when nonlinear power amplifiers are employed. Among the proposed PAPR techniques ...
  • Laguerre-Gaussian beam scintillation on slant paths 
    Yüceer, Mehmet; Eyyuboğlu, Halil T. (Springer, 2012-11)
    Scintillation evaluations for Laguerre-Gaussian (LG) beams for slant paths are made using Rytov approximation. On- and off-axis scintillation is formulated and calculated up to several tens of kilometers of slant distances ...
