  • 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 ...
  • A Sequential Coding Approach for Short Length LT Codes over A WGN Channel 
    Abdulkhaleq, Nadhir Ibrahim; Gazi, Orhan (2017)
    Luby Transform (LT) codes which can be considered as one of the first type of rate less codes are introduced to be an efficient erasure code. In such codes a fountain of encoded symbols is continuously transmitted ...

    Abdulkhaleq, Nadhir Ibrahim; Gazi, Orhan (IEEE, 2017)
    Luby Transform (LT) codes which can be considered as one of the first type of rate less codes are introduced to be an efficient erasure code. In such codes a fountain of encoded symbols is continuously transmitted until ...
  • A survey on belief propagation decoding of polar codes 
    Arlı, Ahmet Cağrı; Gazi, Orhan (2021-08)
    The increasing data traffic rate of wireless communication systems forces the development of new technologies mandatory. Providing high data rate, extremely low latency and improvement on quality of service are the main ...
  • A Tutorial Introduction to VHDL Programming 
    Gazi, Orhan (Springer, 2019)
    This book helps readers create good VHDL descriptions and simulate VHDL designs. It teaches VHDL using selected sample problems, which are solved step by step and with precise explanations, so that readers get a clear idea ...
  • Analog and digital filter design 
    Gazi, Orhan (2018)
    In this chapter, we will study analog and digital filter design techniques. A filter is nothing but a linear time invariant (LTI) system. Any LTI system can be described using its impulse response. If the impulse response ...
  • Analysis of parallel decodable turbo codes 
    Gazi, Orhan (IEICE-INTS Electronics Information Communications Eng, 2012-05)
    Turbo codes suffer from high decoding latency which hinders their utilization in many communication systems. Parallel decodable turbo codes (PDTCs) are suitable for parallel decoding and hence have low latency. In this ...

    Kim, Sung W.; Pan, Miao; Joshi, Gyanendra Prasad; Gazi, Orhan; He, Jianhua; Coupechoux, Marceau (Sage Publications LTD, 2016)
  • Bounds for generalized gamma distributed fading channels 
    Gazi, Orhan (IEEE-Inst Electrical Electronics Engineers Inc, 2011-12)
    In this article, upper bounds for the outage probability and moment generating functions of the fading channels with alpha - mu distribution are derived. The proposed upper bound for the moment generating function is used ...
  • Channel Coding Theorem 
    Gazi, Orhan (Springer, 2018)
