  • Blind equalization of single-input single-output fir channels for chaotic communication systems 
    Vural, Cabir; Çetinel, Gökçen (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
    Recently we have developed a simplified recursive adaptive blind channel equalization method for Single-Input Single-Output (SISO) chaotic communication systems. Even though the simplified recursive algorithm gives superior ...
  • Chaotic Digital Image Watermarking Scheme Based on DWT and SVD 
    Çetinel, Gökçen; Llukman Cerkezi (IEEE, 2015)
    In this study chaos based digital watermarking scheme together with Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) is proposed. In the proposed watermarking scheme, the cover image is decomposed ...
  • RDWT and SVD Based Secure Digital Image Watermarking Using ACM 
    Llukman Cerkezi; Çetinel, Gökçen (IEEE, 2016)
    It is demonstrated via computer simulations that the proposed RDWT, SVD and ACM based digital image watermarking scheme provides better watermark concealment and high robustness against both geometric and image processing ...
  • Signal Processing and Communications Applications Conference 
    Yalcin Albayrak; Çetinel, Gökçen; Gül, Sevda (IEEE, 2017)
    In this study, Electromyogram (EMG) signals obtained in Rectus Femoris and Biceps Femoris muscles are used to trigger Patela-T reflexes in spastic patients. 26 features are derived by calculating five features in both time ...
  • Signal Processing and Communications Applications Conference 
    Yurdagul Karagoz; Gül, Sevda; Çetinel, Gökçen (IEEE, 2017)
    At signal processing stage, after preprocessing step for eye movements (vertical, horizontal and blink) maximum and minimum voltage amplitude values are detected. These values are directly determine the performance of the ...
