  • BIT interleaved coded spatial modulation 
    Kadı, Furkan Kerim. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Spatial modulation is a novel modulation technique that utilize antenna space in addition to symbol space for information transmission. This technique is implemented with the well known BICM system to provide robustness ...
  • Channel polarization with higher - order memory 
    Afşer, Hüseyin. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    Channel coding is one of the most fundamental problems regarding the nature of communication. Polar codes, developed by Ar kan, were the rst demonstration of practical channel codes that provably achieve theoretical limits ...
  • Comparison of multicarrier CDMA with successive interference cancellation and interference cancellation with gibbs sampler 
    Yılmaz, Murat. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    Recently Orthogonal Frequency Division Multiplexing (OFDM) has gained a lot ofattention and is the technology for Fourth Generation (4G) wireless systems because itpromises data rates up to 100 Mbps. A variation of OFDM ...
  • Error performance of line coding 
    Pehlivaner, Gülgün. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1984., 1984.)
    A tutorial overview of line coding techniques under two broat classiFications, neamly linear and nonlinear line codes is presented.A brief discussion of several approaches towards symbol error probability and error perFormance ...
  • Integer programming based analysis of decoding failures for LDPC codes 
    Sarıduman, Abdullah. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    Low-density parity-check (LDPC) codes are one of the most e cient and common error correcting codes thanks to their high error performance. Using iterative messagepassing decoding or linear programming (LP) decoding with ...
  • Picture processing techniques 
    Mergen, Tijen. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1984., 1984.)
    Image processing techniques find applications in many areas, chief among which are image enhancement, picture compression, pattern recognition, efficient picture coding and image understanding. In this master thesis, some ...
  • Reduced-complexity reinforcement learning-based polar code construction 
    Oral, Ezgi. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    Due to the increasing number of users in the communication systems, efficient spectrum usage, high-speed data transfer, and better error performance became a ne cessity. Therefore, it is aimed to design error control codes ...
  • Spatially-coupled LDCP coding for the correlated erasure channel 
    Ashrafi, Mahmood Reza Alizadeh. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    In this thesis, spatially-coupled low density parity-check (LDPC) codes, which have been shown to exhibit the threshold saturation phenomenon over the binary erasure channel (BEC), are considered and a low-delay iterative ...
  • User cooperative communications in ultra-wideband wireless networks 
    Yalçın, Cumhur Ozan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    In this thesis, we consider the user cooperation in ultra-wideband (UWB) systems characterized by severe frequency selective channels. To circumvent this problem we present a space-time (ST) coded UWB system employing the ...
  • VLSI implementation of a new standard for lossless compression of continuous-tone still images 
    Aktürk, A. Suat. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1998., 1998.)
    In this thesis, an integrated circuit realizing lossless compression of continuous-tone still images is designed. Lossless compression has two main parts. In the encoding part, digital source image data are encoded in order ...
