    • Digital implementation of orthogonal frequency division multiplexing 

      Bhanushali, Artiben (Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
      "OFDM (Orthogonal Frequency Division Multiplexing) is the most important part of 4G and 5G technology which is adopted by many standards because of its various advantages. In this thesis, firstly prototype of OFDM system ...

    • Enhancing data efficiency in OFDM (IEEE 802.11a) using equalization (11A) 

      Reddy, S. Gangadhar (Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
      IEEE 802.11a OFDM signal passed through a dispersive channel introduces ISI & ICI. To avoid ISI & ICI, cyclic prefix (guard interval) is introduced between the OFDM symbols. But the cyclic prefix contributes about 20% ...

    • Model based channel shortening technique for IEEE 802.11a OFDM system 

      Patidar, Pravin (Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
      Channel shortening tehniques for IEEE802.11a OFDM system are studied. Their performance is evaluated for various standard channel models. A model based channel shortening technique is presented, which reduces the computational ...
